WebThe diversity of alleles and genotypes within a population is called genetic variance. When scientists are involved in the breeding of a species, such as with animals in zoos and nature preserves, they try to increase a population’s genetic variance to preserve as much of the phenotypic diversity as they can. WebEssentially, anything that increases the variance among individuals in reproductive success (above sampling variance) will reduce Ne (the size of an ideal population that experiences genetic...

Why Should Breeders Consider Genetic COI in Breeding Decisions?
WebThird, low levels of genetic variation can lead to decreased survival and reproductive rates through inbreeding depression. When individuals in a population are very similar to one … WebWhereas inbreeding can lead to a reduction in genetic variation, outbreeding can lead to an increase. Random forces lead to genetic drift Sometimes, there can be random … WebThe isolation of a small population for a period of time can lead to inbreeding within that population, resulting in increased genetic relatedness between breeding individuals. Inbreeding depression can also occur in a large population if individuals tend to mate with their relatives, instead of mating randomly. burly and the bean seaside oregon
