Homozygous refers to an organism having two identical alleles for a given trait. This means that both alleles are either dominant or recessive. Heterozygous means having two different alleles for a given trait. Dominant and recessive refer to the expression of a trait in the presence of multiple alleles, and codominant refers to two alleles that are both expressed equally in the phenotype of the organism.
