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! KEY WORDS Inherited Traits- An inherited trait is a characteristic passed from parents to the offspring or child through genes. Genes- The basic unit of heredity. Different forms of genes are called alleles. Alleles- Alternative form of a gene inherited separately from each parent. (for eye color the allele might result in blue or brown eyes). KEY CONCEPT: All organisms have genes and inherited traits. You have 3 tasks to accomplish for this week's BLOG. A. Read the article (use the link) and answer the following questions in complete thoughts. 1. What are inherited traits? 2. How many pairs of chromosomes are found in a human cell? How many genes? 3. How do you know if you have a recessive trait? B. Watch the video (use the link) and answer the following questions in complete thoughts. 1. What is the structure & function of chromosomes? 2.

A inherited trait is a characteristic passed from a parent to a child.
There are 23 chromosomes in a human cell. And there are 35,000 genes.
You notice you have something that your parents have.
B.
1.) The structure of chromosomes is a long strand of DNA and its function is to create traits.
2.) Human cells have 46 chromosomes and sex cells have 23 chromosomes.
3.) Down Syndrome is an inherited condition. You can't just get it, someone in your family would have to have it.
C.
1.) DNA.
2.) Because genes are passed down from generations like a family recipe
3.) Humans: 46.
Horses: 64.
Chimpanzees: 48.
Monkeys: 21.
Cows: 30.
Chickens: 39.
Bananas: 11.

2. There can be 23 pairs of chromosomes in a cell and 35,000n genes in a cell.
3. You know you have a recessive trait if you act dominant and recessive.
B. 1. The structure of a chromosome is a long cell that curls itself up. Its function is to hold your DNA which determines eye color hair color and other traits.

1.) Inherited traits are things that are similar between both parents that are given to the children.
2.) A human cell contains 23 pairs of chromosomes and 35000 genes.
3.) When both are alleles are recessive.
4.) Chromosomes are cells that come from the mom and dad, which each person has 46. 23 from each parent. In a sex cell there is only 23, and not 46 like chromosomes. People get Down ’s syndrome because there are not enough cells to make and pair up.
5.) Genes are part of your DNA. Genes are like family recipes because they go on and on throughout the whole family. Monkeys have 21 pairs, cows have 30 pairs, chickens have 39 pairs, bananas have 11 pairs, humans have 23 pairs, chimpanzees have 24 pairs,
A} inherited traits are traits you inherit from other family members. 23 pairs of chromosones and 35,000 genes.When more than a single gene determines traits, other more complicated interactions occur.
B}1. the sturcture of chromosones is in the shape of a DNa stran. A body cell is somthing that you inherit and the sex cell is somthing when you inharit somthing from both your parents. people get down's syndrom by having a missing chromosones.
C} Genens are part of DNA. genes are like a family recipe beceause only your family may have the same genes. a human has 23, a horse has 64, a chimpanzze has 48, a monkey has 48, a cow has 60, a chicken has 38, a banana has 65.
