Why is understanding Heredity important?

Heredity is the passing of human characteristics to offspring so its important because it is how you look like from your parents genes from DNA. Your genes can be dominant(strong) with your traits or you can get a recessive(weak) trait. And you start to inherit traits from your parents. Which you get your characteristics from.

In the egg from Mom and the sperm from Dad, they each carry 23 chromosomes(46 in total). Each chromosomes holds DNA and each piece of DNA is a gene and they pair up with your Moms and Dads and each gene pair gives a trait. For ex. if 1 of your parents had black hair and the other parent had brown hair, it will depend on who has the stronger genes so you will get there hair color more. It is important because its is how you will look in life and how people look at you.
