WebMar 7, 2024 · The result of homozygous is always the same; pure for a particular trait and breed. For heterozygous, an individual isn’t pure and the offspring usually has different genotypes. In homozygous, an individual may carry a dominant or recessive allele, but one at a time. with heterozygous, the individual can have one dominant and one recessive ... In Mendelian genetics, this means that an organism must be homozygous for every trait for which it is considered true breeding; that is, the pairs of alleles that express a given trait are the same. In a purebred strain or breed, the goal is that the organism will "breed true" for the breed-relevant traits.
