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) Alleles are copies of the original.
5) He noticed that a tall plant could have a recessive trait for shortness that we could not see.
B)
1) Genes that control a trait come in pairs.
2) Blue Eye Color and Brown Eye Color.
3) They only show up when there is no dominant allele present.
C)
1) The phases of the cell cycle are G1, S, G2, Mitosis.
2) Chromosomes line up in the center so they can pull the fibers into a line in the middle.
3) IT is important because if they didn’t separate, the cell would not separate and divide.
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.

1. Gregor Mendel was considered the father of genetics because he made many discoveries about genetics.
2. Mendel described dominate traits as traits that appeared more often. He described recessive traits as traits that showed up less often.
3. Mendel described hybrid plants as a plant that has two different alleles.
4. Alleles are two copies of traits.
5. they are plump vs. wrinkled pod, round vs. wrinkled pea, green vs. yellow pea, green vs. yellow pod, and white vs. purple flower.
B.
1. Genes that control traits come in pairs.
2. One type of allele is dominate. Another type of allele is recessive.
3. Recessive alleles only show up if there is no dominate allele present to suppress them.
C.
1. The phases of the cell cycle are G1, S, G2, Mitosis.
2. The chromosomes line up at the center of the nucleus because they need to pull the fibers into a line in the middle.
3. It is important for the chromosomes to separate before the cell divides because if they did not seperate the cell would seperate and divide.
A1. He is considerd the father of modern genetics because he disaverd genetics.
A2. He discribed it by saying that the bigger letter is the dominate and the little letter is the resesive trait.
A3.He explaind it by saying hybrid plants are plants that came from a purebred and a hybrid plant.
A4.Alleles are things that show the types of traits that they are going to get.
A5.He obseverd traits that showed how tall or how short the pea plants will get.
B1.Genes that control traits come in control when a trait is about to die.
B2.The two types are dominate and resesive
B3.They only show up when there is a parent with a resesive trait.
C1.The phases are birth then they become part of the body.
C2.They line up in the nucleaus because they are trying to get the cell to reproduce.
C3.It is important because if they dont they will seperate along with the cell.

A. 1. He found put how hybrid and purebred works and all about recessive and dominant traits worked. This was a modern advancement because no one knew much about it.
2. The ones that showed up more often were dominant and the ones that showed up less were recessive.
3. They were a mix of two plants and would have two traits for a gene so it could be tall but the recessive would short so it had two of each.
4. Alleles are two copies.
5. Some pea pods were wrinkled and some were smooth. Some were green some were yellow. Some flowers were purple others were white.
B. 1. The genes that control come in pairs one from dad one from mom.
2. Two types of alleles are dominant and recessive.
3. Recessive alleles can only show up if there is no dominant allele to suppress it.
C. 1. The first phase is called G1 where it grows larger. After growth the cell duplicates itself. This is called the s phase of the cycle. The DNA is then checked by enzymes for mistakes and repairs. This is the G2 phase of the cycle. When ready cell division begins this is called mitotis. Mitotis begins when the nuclear membrane dissolves and the DNA thickens. Special fibers called spindle fibers form from each side of the cell and grow towards the DNA chromosones.
2. They are in the center so they can pull fibers into a line in the middle
3. If it doesn’t separate in time it the cell would not separate and divide properly.

A1.) George Mendel is considered to be the father of modern genetics because he relized that peas can grown in difforent sizes.
2.) He said that "dominant traits showed up more often than recessive traits.
3. He said that Hybrid plants are different from dominant plants.
4.) They are copies.
5.)Tall plantys could have a recessive trait that does not let us see it's shortness.
B1.)They come in pairs.
2.)Green eyes and Hazel eyes.
3.)They only show up if there is no dominant traits.
C1.)The phases are G1, S, G2 mitotis.
2.)Chromosomes line up to pull fibers in the middle.
3.)If they don't then then the cell will not seperate

1. Why is Gregor Mendel considered the father of modern genetics? He is Considered the father of modern genetics because he found out about traits and genes
2. How did Mendel
describe dominant and recessive traits? That dominant traits showed up more and that recessive traits showed up less
3. How did Mendel explain hybrid plants? That each gene has two chances at a trait
4. What are Alleles? A Alleles is a copy.
5. What traits did Mendel observe in tall versus short pea plants? Plump vs. wrinkled pod, round vs. wrinkled pea, green vs. yellow pea, green vs. yellow pod, 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? Dominant and recessive
3. Recessive alleles only show up if? When there is no dominant trait
C. Watch the video (use the link) and answer the following questions in complete thoughts.
1. List the phases of the cell cycle. The first phase is A resting phase where the cell has left the cycle and has stopped dividing. The second phase is where cell increases in size. The third phase is where dna rplication occurs. The fourth is where they make sure everything ready. The last phase is when cell growth stops
2. Why do the chromosomes line up in the center of the nucleus? Cell growth stops at this stage and cellular energy is focused on the orderly division into two daughter cells. A checkpoint in the middle of mitosis ensures that the cell is ready to complete cell division.
3. Why is it important for the chromosomes to separate before the cell divides? So the cells that divide get the right genetic information
A1- Gregor Mendel is the father of genetics because he made some huge discoveries while breeding peas.
A2- He described dominant traits as they show up more often and recessive show up less.
A3- He explained hybrid plants as a mix.
A4- Alleles are two copies of the same trait.
A5- Mendel observed that the short plants have wrinkled pods and peas that are yellow verses the tall plants that are plump and green.

B2- Two types of alleles are blue and brown eye color.
B3- Recessive traits only show up if there are no dominant traits.
C1- The phases of a cell: G1, S, G2 and mitosis.
C2- Chromosomes line up in the middle so they can pull fibers in the line.
C3- It is important for the chromosomes to seperate before the cell divides because if they didn’t separate, the cell would not separate and divide.

A1.) He’s considered the father of modern genetics because he had discoveries about genetics from growing peas.
A2.) Dominant traits appear more often and recessive traits show up less often.
A3.) That if short and tall plants breed they become a hybrid plant.
A4.) Copies of genes.
A5. ) Plump vs. wrinkled pod, Round vs. Wrinkled pea, Green vs. Yellow peas and pods.
B1. ) Genes that control traits come in pairs.
B2.) Blue eye color and Brown eye color.
B3.) Recessive alleles only show up if there are no dominant alleles.
C1.) Cells reproduce through cell division. There is a chemical signal for reproduction. Then the cell grows larger. The DNA is then checked by enzymes. Then cell division begins.
C2.) The fibers attach to centromeres on the chromosomes, and pull me into the center.
C3.) It’s important because they would not be able to reproduce right away if they didn’t.

1.)Gregor Mendel was considered as the father of genetics because he was the first one to understand how DNA worked. Mendel was famous for working with pea plants. He breeded different kinds of pea plants to get certain kinds of colors of peas.
2.)In his experiment Mendel marked with capital letters dominant traits and with small letters recessive traits
3.)He explained them as a mix.
4.)An allele is an alternative form of a gene that is located at a specific position on a specific chromosome.
5.)Tall plants were more plump and they were green.
