Answer 1: An inherited trait is a trait that you have from birth.
Answer 2: 23 pairs of chromosomes but up to 35,000 genes.
Answer 3: Both alleles have to be dominant and recessive for you to have a recessive trait.
B.

A.
1.What are inherited traits?
Ask someone where he got his red hair from and he will likely tell you that he inherited it from one of his parents or grandparents. However, when someone says that her tendency to be messy came from a grandparent, should we assume that messiness, too, is an inherited trait? Some traits exist from birth, while others are learned from our environment. Some inherited traits remain obvious, such as eye color. But there are other more obscure inherited traits that you may never have thought about, such as a certain digit's ability to bend.
2. How many pairs of chromosomes are found in a human cell? How many genes?
There are 23 chromosomes found in just one human cell and there are 35,000 genes in as human cell.
3. How do you know if you have a recessive trait?
You can find out by asking your parents if they could do a special trait then see if you could do it, if you can then you have a recessive trait.
B.
1. What is the structure & function of chromosomes?
It is a very long strand of DNA.
It tells your traits and characteristics.
Carrys genetic information.
2. What is the difference between a body cell and a sex cell?
For the body cell there is 46 chromosomes. For the sex cell there is 23 chomosomes.
3. How do people get Down's Syndrome?
People get Down Syndrome by only having an extra chromosome.
C.
1. Genes are part of what?
The Nucleous.
2. Explain how genes are like family recipes?
They are like a family recipe because they are passed down from generation to generation.
2. How many chromosomes do the following organisms have:
• humans – 46 chromosomes
• horses – 64 chromosomes
• chimpanzees-48 chromosomes
• monkey's- 42 chromosomes
• cows- 60 chromosomes

Eat your vegetables, before they eat you!
This week we will be learning about genetics. Earlier we learned about traits and characteristics and how they affect the appearance of an organism. This week we will be focusing on inherited traits, genes and alleles. We will also be setting up an experiment that shows how these inherited traits are passed from parent to offspring in plants!

Melissa and Miranda
A)
1. Inherited traits are traits you inherit from someone connected to you by blood.
2. There are 23 pairs of Chromosomes in a Human Cell. There are up to 35000 Genes in a Human Cell
3. You can know if you have a recessive trait by having both Allies recessive by a single gene from someone connected to you by blood.
B)
1. A chromosome is a long strand of DNA that contains the information that makes individuals unique.
2. Body cells range from doing work as a heart cell to being a liver cell. Body cells have 46 chromosomes.
Sex cells are only used for reproduction.
Sex cells have 23 chromosomes, so that they can be matched up with another sex cell to form a body cell.
3. People get Down syndrome by not having enough chromosomes
C)
1. genes are part of DNA
2. Because your genes come from people connected to you by blood. You cannot get genes from someone not connected to you by blood. Kind of like a family recipe, no one else knows about it. Its passed down from generation to generation.
3. humans – 46 Chromosomes
Horses- 64 Chromosomes
