Webb8 juni 2024 · Figure 19.2 A. 1: Low genetic diversity in the wild cheetah population: Populations of wild cheetahs have very low genetic variation. Because wild cheetahs are threatened, their species has a very low genetic diversity. This low genetic diversity means they are often susceptible to disease and often pass on lethal recessive mutations; only ... WebbIn biology, mating is the pairing of either opposite-sex or hermaphroditic organisms for the purposes of sexual reproduction. Fertilization is the fusion of two gametes .

WebbWhether non-random mating counts as an agent of evolution is up for debate because the allele frequencies in the gene pool stay the same. Allele frequencies can change if those with certain traits are able to reproduce at a higher rate , but in that case, natural selection will also be an agent of evolutionary change. Webb3 juni 2024 · Random mating: Totally haphazard mating, with no regard to the genetic makeup ( genotype) of the mate, so that any sperm has an equal chance of fertilizing any egg.
