An example of a homozygous genotype is "AA" or "aa" for a particular trait. In genetics, a homozygous genotype consists of two identical alleles for a specific gene, meaning the individual carries the same variant from both parents. For instance, if a pea plant carries two dominant alleles (AA) for flower color, it is homozygous for that trait. This is important in genetics as it affects the expression of traits and can influence breeding outcomes in plants and animals.
