Recombination Frequency
Recombination frequency measures the likelihood that alleles at different loci will be separated during meiosis, expressed as a percentage or map distance in centiMorgans (cM). In cannabis breeding, this metric helps breeders understand genetic linkage patterns—whether desirable traits tend to be inherited together or separately across generations. Higher recombination frequencies (closer to 50%) indicate genes assort independently, while lower frequencies suggest genes are physically close on the chromosome and tend to be co-inherited. Breeders use recombination data to predict offspring phenotype distributions, plan crosses more strategically, and identify whether favorable trait combinations are genetically linked or will require additional selection rounds to achieve.

Understanding recombination frequency allows breeders to model expected trait segregation in F2 and later generations, informing decisions about population size, selection intensity, and cross strategy. Low recombination between target loci can lock desirable trait packages together, while high recombination offers flexibility to reassort traits across new combinations.
