Is inbreeding really efficient at producing homozygosity?

WebInbreeding is defined as matings between individuals in a population that are more closely related than expected by chance. The inbreeding coefficient, f, describes the probability that two alleles at a locus are identical by descent. This is to say, both are copies of one particular allele inherited by common ancestry. WebNon-random mating. In non-random mating, organisms may prefer to mate with others of the same genotype or of different genotypes. Non-random mating won't make allele frequencies in the population change by itself, though it can alter genotype frequencies. raymond nh town election results 2023

WebTwo other important exceptions are inbreeding (mating with relatives) and enforced outbreeding. Both can shift the equilibrium proportions expected under Hardy-Weinberg calculations. For example, inbreeding increases the proportions of homozygotes, and the most extreme form of inbreeding, self-fertilization, eventually eliminates all heterozygotes.

"WebInbreeding is the mating of individuals that are related. In the strict sense, all members of a breed are related. As a result, any seedstock producer is practicing some inbreeding.
