homozygous dominant
Both alleles (factors) for a trait are the same and dominant (AA)
Homozygous dominant refers to an individual who has two copies of the same dominant allele (version of a gene) for a specific trait. This individual will express the dominant trait, as there is no recessive allele to compete with it. For example, if the dominant trait is brown eye color and the recessive trait is blue eye color, a person who is homozygous dominant for eye color would have two dominant brown alleles and therefore, would have brown eyes. This type of genetic makeup is represented by the letters “BB” in a Punnett square or genetic diagram. It’s important to note that homozygous dominant individuals are purebred for a specific trait, meaning they will only pass on the dominant allele to their offspring.
