Now, what about homozygous? What does it mean for individual or organism to be homozygous for some given trait? Well, there are two possibilities for this type of genotype we have an individual organism is said to be homozygous one or two cases. So either both of those alleles are actually dominant or both of those alleles are actually recessive. In the case that they're both dominant, this is known as homozygous dominant. In the case they're both recessive, that is known as homozygous recessive.
