Gene
From the Simple English Wikipedia, the free encyclopedia that anyone can change
A gene is a hereditary unit consisting of DNA that occupies a spot on a chromosome and decides a characteristic in an organism.
Half of a person's genes come from the mother. The other half come from the father.
Genes are passed on from parent to child and are an important part of what decides the biological properties of offspring (children).
Genes affect the way our bodies work, including how we look. So our eye, hair and skin color is caused by genes. It is said that genes cause genetic effects in our bodies.
