Heterozygous - When two different alleles combine to form a trait. Example: A tall person and a short person have a child who is short. The short allele is dominant so the child grew up to be short. Gene - A section of DNA that controls a certain trait. Example: Eye color. Dominant - Determines the expression of a trait (visually). Example: Brown eyes, dark hair. Homozygous - A homozygous trait is when two of the same kind of alleles combine to form a trait. Example: When two tall people ...
