How are Traits Passed from Parents to Offspring
... A trait is a characteristic such as color or size that is inherited by an offspring from its parents. The genes that control a trait come in pairs, one gene from each parent. We represent these gene pairs by writing a combination of two capital letters. For example, if one parent contributes a gene ...
