In genetics, homozygous refers to a genotype with similar alleles, either homozygous dominant or homozygous recessive.
When a plant is homozygous-dominant for a particular cannabis characteristic, its genotype is denoted by doubling the trait’s symbol, which is two uppercase letters. On the other hand, two lowercase letters represent homozygous recessive traits in the cannabis seeds.
Cannabis plants with homozygous traits are generally considered stable traits because the traits are held constant.
