The coefficient of relatedness (r) is defined as the probability that a gene in one individual is identical-by-descent (IBD) to a gene in another individual. In other words, it is the probability that two individuals inherited a certain proportion of genes from a common ancestor.

WebThe Breeder's Equation. R is the response to selection, S is the selection differential, and h 2 is the narrow-sense heritability. This is the workhorse equation for quantitative genetics. The selective differential S, is the difference between the population average and the average of the parental population (some subset of the total population).
