Inbreeding Coefficient
Inbreeding coefficient (IC) is a quantitative genetics metric that measures the proportion of homozygous alleles in an individual plant relative to a reference population. In cannabis breeding, IC values range from 0 (completely outbred) to 1 (completely homozygous), with higher coefficients indicating tighter genetic relationships between parent plants. Breeders calculate IC to track genetic diversity within their lines and predict trait expression stability across generations. This metric is distinct from phenotypic traits but directly influences phenotypic uniformity, vigor, and the probability of recessive allele expression in offspring.

Breeders use inbreeding coefficient data to make informed decisions about line stabilization, hybrid vigor management, and risk assessment for inbreeding depression. Understanding IC helps breeders design crosses that balance genetic fixation of desirable traits with maintenance of heterozygosity for overall plant health and adaptability.
