Question

Quizplus · Accepted Answer

Inheriting from parents similar genes for a given trait is referred to as being homozygous for that trait. In this example, Ayman's parents both have black hair and brown eyes, dominant traits. Therefore, without knowing their genotype, we cannot be sure of Ayman's genotype. However, assuming that Ayman has received similar genes from both parents, he would then be considered homozygous for those traits.
