Notice not one person looks exactly the same, everyone is unique. Why? Because everyone has something called “traits”. A trait is a specific characteristic of someone, whether it be their hair, eye color, blood type, ect. A trait is also the same as phenotypes, physical traits, and genotypes. Traits are something that are genetically inherited from your parents. (Krasnewich) If a guy has brown eyes(dominant) and his wife has blue eyes(recessive), their child is most likely going to have brown eyes because that is the dominant trait.
