Difference Between Homozygous and Heterozygous
The key difference between homozygous and heterozygous is that homozygous means both alleles are similar for a trait while heterozygous means the two alleles are different for a trait.
The genes inherited from the parental chromosomes control all the characters or traits of animals, plants, and all other living beings. It is the core reason for showing parental characteristics in the progeny. Most eukaryotic organisms have two sets of genes known as maternal genes and paternal genes.
