Homozygous Vs Heterozygous
Homozygous and heterozygous refer to the genetic composition of alleles at specific loci in a cannabis plant's DNA. A homozygous individual carries two identical alleles for a given trait (e.g., AA or aa), while a heterozygous individual carries two different alleles (Aa). In breeding programs, homozygous lines are prized for stability because they reliably produce offspring expressing the same phenotype across generations. Heterozygous plants often display hybrid vigor or intermediate trait expression, making them valuable for F1 hybrid development. Understanding this distinction is fundamental to selective breeding, line stabilization, and predictable seed production.

Breeders pursuing true-breeding, stable strains work toward homozygosity across target traits through repeated self-pollination or backcrossing. Conversely, breeders capitalizing on heterosis deliberately maintain heterozygous F1 hybrids to maximize uniformity and vigor in commercial seed batches.
