Core D, Unit D, Genetics Blog 2









This week we will be learning a little history about genetics and the father of genetics Gregor Mendel. We will also practice what we learned about how parents pass traits on to their offspring using punnet squares.  Finally, you will be introduced to the cell cycle, mitosis, and meiosis.

A.     Read the article and use the link below to answer the following analysis questions in complete thoughts.


1.    Why is Gregor Mendel considered the father of modern genetics?
2.      How did Mendel describe dominant and recessive traits?
3.       How did Mendel explain hybrid plants?
4.       What are Alleles?
5.       What traits did Mendel observe in tall versus short pea plants?

B.     Use the following link to answer the following questions in complete thoughts.  Then practice completing punnett squares until you can do 3 punnet squares perfectly!


1.       Genes that control traits come in?
2.       What are the two types of alleles?

1. Gregor Mendel is considered the father of modern genetics because he discovered many facts while breeding peas.
2. He described them that some traits showed up more often and he called them dominant traits. The traits that showed up less often he called recessive traits.
3. He described it as if tall plants and short plants bred, they would have made a mixed plant.
4. Alleles are where a gene has two chances at a trait.
5. The traits that Mendel observe in tall versus short pea plants are…
-plump vs. wrinkled pods
-round vs. wrinkled peas
-green vs. yellow peas
-green vs. yellow pods
-white vs. purple flowers
B.
1. Genes that control traits come in pairs
2. Two types of alleles are dominant and recessive.
3. The recessive trait only shows up if the alleles are both lower case.
C.
1. The phases of the cell cycle are…
-It gets a chemical signal for preparation of reproduction
-The cell grows larger which is called G1
-It duplicates its DNA which is called the S phase
-The DNA is checked and repaired which is called the G2
-When ready the cell begins to divide which is called Mitosis
-Finally it divides
2. Chromosomes line up in the center of the nucleus because they are going to be pulled apart by spindle fibers.
3. It is important for the chromosomes to separate before the cell divides so each cell has the same DNA in it.

A1. It is because he discovered the genetics.
2. He described them by saying dominant traits show up more and recessive traits show up less often.
3. He said hybird plants are short and tall bred mixed.
4. Alleles are that each gene has two chances at a trait - two copies
5. Short vs. Tall- plump vs. wriknkled pod, round vs. wrinkled pea.

B1. They come in pairs
2. Blue eye color and brown eye color.
3. If there is no dominant allele.

C1. The phases of the cell cycle is G1, S, G2, and Mitosis
C2. Chromosomes line up in center so they can pull the fibers into a line in the middle.
3. It is important because if they didn't seperate, the cell would not seperate and divide.

A.

1. He is considered the father of modern genetics because he discovered that the peas in his garden had the same traits of the parent.

2. He described them by showing how if two different plants bred then it would make the offspring different.

3. A hybrid plant could be carrying different alleles when they make new offspring’s.

4. Alleles are two copies of one gene.

5. The traits were that the new plant was medium size and wasn’t very good growing.

B.

1. They come in pairs.

2. The two types of Alleles are dominant and recessive.

3. They only show up if there is no dominant allele.

C.

1. They form from other cells, live on carrying the nutrients and blood to where it needs to go then the eventually die, and new cells are formed.


2. They line up because the chromosomes are the power of the cell so they need to give power to the nucleus.

3. It’s important because when they separate the create two new nuclei.

A. Read the article and use the link below to answer the following analysis questions in complete thoughts.

1. Why is Gregor Mendel considered the father of modern genetics?
2. He discovered (with plants) that there are several traits and they have dominated and recessive traits, he learned that if he bred theses that it would create a hybrid.
3. How did Mendel describe dominant and recessive traits?
4. Dominate traits show up more and recessive traits show up less often.
3. How did Mendel explain hybrid plants?

What are Alleles?
Alleles are two copies or like chances at a trait.
5. What traits did Mendel observe in tall versus short pea plants?
Plump vs. wrinkled pods, round vs. wrinkled pea, green vs. yellow pea, white vs. purple flower.
B. Use the following link to answer the following questions in complete thoughts. Then practice completing punnett squares until you can do 3 punnet squares perfectly!

1. Genes that control traits come in?
They come in pairs.

2. What are the two types of alleles?
The two types of alleles are dominate and recessive.
3. Recessive alleles only show up if?
Recessive allele can only show up when there is no dominate trait present.


C. Watch the video (use the link) and answer the following questions in complete thoughts.

1. List the phases of the cell cycle.
The cell grows larger and it is called the G1 phase of a cells life. Then the cell duplicates its DNA. This is called the S phase of a cells life. The DNA is then cheeked by enzymes for mistakes and repairs. This is called G2 phase of a cells life. When ready cell division begins this is called mitosis of a cells life.
2. Why do the chromosomes line up in the center of the nucleus?
So the fibers can attach to centromers on the chromosomes and pull them into a line in the middle of the nucleus.
3. Why is it important for the chromosomes to separate before the cell divides?
So that we can start out as a single cell and then divide again and again

A.
1. Gregor Mendel is considered the father of modern science because he made some big discoveries.
2. The ones that showed up more he called them dominate and the ones who showed up last were called recessive.
3. If tall plants and short plants bred they make a mixed hybrid of offspring plant.
4. Means 2 copies.
5. He observed plumb vs. wrinkled, round vs. wrinkled, green vs. yellow, green vs. yellow pod, white vs. yellow flower.
B.
1. Creeeaaaamm!!
2. Sharp teeth vs. smiling teeth, claws vs. no claws
3. If there’s two dominante traits
C.
1. There’s a chemical signal that sends a sign for reproduction, it grows larger called G1 phase, then dupilicats called the S phase, checked by enzymes for mistakes and repairs called the G2, begins it’s mitosis, the cells divide, last they divide into two called telophase.
2. They are pulled apart by spindel fibers
3. So they have the same DNA

Adam S said...

A.
1. Mendel discovered how to breed pea plants using genetics.
2. Dominant traits are seen more than recessive ones.
3. Hybrids happened when a tall plant breeded with a short plant and their offspring was tall, but also had the recessive trait of a short plant that you do not see.
4. Copies of a trait
5. Tall plants were dominant to short plants.

B.
1. Genes that control traits come in pairs.
2. Dominant and recessive.
3. Recessive only shows up if both parents had the recessive gene.

C.
1. G1 - Cell grows larger. S - Cell duplicates its DNA. G2 - DNA is checked and repaired. Mitosis (M) - Cell divides.
2. SO they can seperate properly.
3. If the chromosomes do not seperate then the cell will die.

Allison Burst and Katelyn Evans
A – 1 He was a monk and made big discoveries about genetics.
2 Dominant- showed up more, recessive- showed up less
3 Tall and short plants bred and mixed together he called a hybrid plant.
4 They are two copies
5 He observed short, tall, wrinkled, smooth, green, yellow.

B-1 Genes that control traits come in pairs
2 The two alleles are dominant and recessive
3 recessive alleles only show up if there is no dominant allele to suppress them

1. They reproduce through cell division so they are asexual, they then go through a phase called “G1”, which is when they grow. The cell then duplicates its DNA, through the “S phase.” The DNA is then checked by the enzymes for any mistakes and repaired, this is called the “G2 phase”. The cell then divides, this process is called Mitosis.

2. They line up because they get separated in 2 for reproduction.

3. To make sure each new cell has the same genetic information.

A
1. He found out how resesive and dominate traits work and how when some mix they can make a hybrid (a dominate trait parent and a resevive parent) then a purebread (Parents with only the dominate trait OR resesive trait)

2.He said when some traits show up more poften its a dominate trait, when they show up less its resesive.

3.Mendal said that hybrid plants are plants with parents who have two diffrent traits.

4) Alleses- are two copies of one thing.

B
1. They come in pairs.

2.Two things of Alleles are resesive and dominate

3.They can only show up if there is no dominant allele

C.
1. The phases of the cell cycle;It gets a chemical signal for preparation of reproduction
And the cell grows larger which is called G1. Then it duplicates its DNA called the S phase.
The DNA is checked and repaired which is called the G2. When ready the cell divides, called Mitosis

2. they are going to be pulled apart by spindle fibers

3. It is important for the chromosomes to separate before the cell divides so each cell has the same DNA in it.

A)
1) George Mendel is considered to be the father of modern genetics because he discovered that peas can vary in shape and size depending on their genetics. He made multiple discoveries about genetics while he was harvesting his peas.
2) Mendel described dominant traits that they were the traits that showed up more often and that the recessive traits are the ones that show up less often.
3) He said that hybrids plants where created when a tall plant and a short plant bred.
4. Two copies.
5. Plumped and wrinkled pod, round and wrinkled pea, green and yellow pea, and white and purple flower. 1. They come in pairs.

2. The two types of alleles are dominate and recessive.
3.Recessive allele can only show up when there is no dominate trait present.

A)
1. He discovered Modern Genetics.
2. The traits that showed up more often were dominant. The traits that showed up less often were called recessive traits.
3. If short and tall plant breeds mixed together then they would create hybrid offspring plant.
4. Alleles are two chances at a trait in a gene.
5. Plump vs. wrinkled pods, Round vs. wrinkled peas, green vs. yellow peas, green vs. yellow pod, white and purple flower.
B)
1. Pairs
2. Dominant and Recessive
3. If the organism if homozygous
C)
1. G1 , G2 , Mitoses .
2. So they can travel through your body .
3 . So they can get through your bloodstream faster .

SECTION A
1. The way Gregor Mendel is Known as the father of modern genetics because he found out about dominant and recessive traits.
2. The ways Mendel described dominant and recessive traits are dominant traits are seen more often. And recessive traits are seen less often.
The way Mendel described hybrids is by saying they are mixed bread.
Alleles are like duel copies.
The traits that Mendel studied in various pea plants between tall and short ones are the height, the pod size and color, pea color/ shape, the color of the flower, and the plumpness of the pod.
SECTION B
1. The traits that come in and take control are the dominate traits.
2. The two types of alleles are the letters that are shown are the same and the way it looks.
3. The recessive alleles only show up if the letters are both lower case.
SECTION C
1. The phases of a cell are the splitting, moving, and the death.
2. The reason why the chromosomes line up in the nucleus is to tell it to separate the cell.
3. The reason why the chromosomes split before the cell dose is so the cell looks like the first cell.

A1. Gregor Mendel is the father of modern genetics because he found many great discoveries about genetics. He also was the first person who ever studied genes.
2. Traits that showed up more often they would be dominate and if they showed up less often then they would be recessive.
3. If tall plants and short plants bred, they made a mixed or hybred offspring plant.
4. Aliens meaning copies.
5. Mendel observed that tall plants could still have a short trait that was recessive
B1. Genes that control traits come in pairs.
2. dominant and recessive are the two types.
3. When there is no dominate allele.
C1. The phases of the cell cycle are first growth phase, synthesis phase, second growth phase, and mitotic phase.
2. the fibers attach to centromeres on the chromosomes.
3. If it doesn’t separate in time it the cell would not separate and divide properly.
