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 Most common form of non-random mating Inbreeding refers to mating among closely related individuals (e.g. relatives), and results in deviations from HW equilibriumas a result of anincrease in homozygosity(or heterozygote deficits).

WebNon-Random Mating: Inbreeding Inbreeding, also known as consanguineous mating, is a form of non-random mating in which individuals preferentially mate with relatives who share a greater proportion of alleles with one another than with a random member of a population. Webinbreeding potential for this fungus is high, we found little evidence for inbreeding, with only two pairs of the randomly chosen isolates having identical genotypes at the 34 loci examined. This work highlights the importance of further attempts to resolve important aspects of the morel life cycle regarding heterokaryosis and inbreeding potential.
