Heterozygosity Retention
Heterozygosity retention refers to the preservation of genetic diversity within a cannabis line across multiple generations, rather than stabilizing toward homozygosity. Breeders working in this category intentionally maintain mixed alleles at key loci to preserve phenotypic range, vigor, and adaptive potential. This approach contrasts with traditional inbreeding strategies used to lock in specific traits. Lines bred for heterozygosity retention often display higher phenotypic variation between individual plants, even within the same seed batch. This trait family is particularly relevant in breeding programs prioritizing genetic resilience and avoiding inbreeding depression.

Breeders employ heterozygosity retention when seeking to maintain genetic stability without reducing population vigor, or when developing foundation stock for future crosses. This technique is common in programs aiming to preserve heirloom diversity while producing commercially viable seeds.
