Inbreeding is a form of non-random mating
WebInbreeding is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically. [2] By analogy, the term is used in human reproduction, but more commonly refers to the genetic disorders and other consequences that may arise from expression of deleterious or recessive traits resulting from ... WebInbreeding is the breeding of closely related individuals; for example, two cousins may mate. This type of mating can lead to an increased risk of genetic problems and a decreased diversity within the gene pool. In sum, the three types of non-random mating are assortative mating, disassortative mating, and inbreeding.

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.
WebSep 8, 2024 · Non-random mating means that mate selection is influenced by phenotypic differences based on underlying genotypic differences. In some species, males acquire harems and monopolize females. (Elk, elephant seals, horses, lions, etc.) Is inbreeding an example of random mating? WebDec 4, 2024 · In polygynandrous species, competition for mating by social rank can lead to assortative mating. However, although not an individual trait, social bonds also influence mating opportunities resembling assortative mating. Stump-tailed macaques form long-term close bonds and organize in a linear dominance–subordination hierarchy.

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.

In non-random mating, organisms may prefer to mate with others of the same genotype or of different genotypes.

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