An individual first begins as the union of the sperm from a male and the egg of a female. Both parent contribute their share of genetic material. Genes are found inside cells and they act like code givers with instructions as to how cells must function.
Genes from your parents determine how tall you are, what color hair you have and all the other physical characteristics you have.
Many of us inherit abilities and behavior traits from our parents. This is why in some families they have artistic, musical or other abilities. Many of the things we are able to do came from the genetic code passed on to us from our parents.
