Homozygous describes having identical alleles for a trait, while heterozygous indicates different alleles. It is essential to understand these terms to grasp genetic inheritance concepts.
Homozygous describes an organism that has identical alleles for a trait. For instance, if a plant has two alleles (let's say GG) for a specific trait like plant height, it would be homozygous for that trait. On the other hand, organisms with two different alleles for a gene are called heterozygous.
