Heterozygous

Imagine you're trying to decide what to have for breakfast, but you can't choose between pancakes and cereal. This dilemma is similar to the concept of being heterozygous, where an organism has two different alleles for a trait, just like you have two different breakfast choices. In this analogy, the pancakes and cereal represent the two different alleles; just as you have to decide how to express your breakfast preference, an organism with heterozygous alleles must determine which trait to express, or sometimes it might show a blend or a dominant one, just like when you might decide to have pancakes today and cereal tomorrow.
