In some species, males acquire harems and monopolize females. (Elk, elephant seals, horses, lions, etc.) Is inbreeding an example of random mating?

What are the three types of non random mating?

WebThe inbreeding coefficient (often abbreviated as F) is also called the fixation index. F is the probability that the two alleles of a gene pair in a diploid individual are identical by descent, meaning that they were derived from a common ancestor in past generations. Figure 15. 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. sign into my xfinity email account
