A trait that can be overridden by another trait.

For example, red hair is a recessive trait. If you have one gene for red hair, and one gene for any other color of hair, you will not have red hair. Your hair will be the color determined by the other gene. Therefore, you could have several generations without that trait showing up, until two parents, each with one gene for that trait have a Chile, the child will have a 1 in 4 chance of having that trait.

if parent 1 has 1 gene for red hair (we'll call it R) and one for blond hair (we'll call it B, and the other parent has 1 R and one gene for black hair (we'll call it Bl). there are 4 possibilities for what a child will have for hair color. B, Bl (Black hair with recessive blond); B, R (Blond hair with recessive red); R, Bl (Black hair with recessive red); R, R (Red hair)
