Document Summary
Parents in inbreeding populations are more likely to be related to one another. This means that there is a higher change of sharing and passing on rare. Probability that two alleles are identical by descent recessive alleles. More likely than the rare alleles are brought together which can be deleterious. This inbreeding reduces lifespan as the coefficient increases. Inbreeding increases change that loci are homozygous for alleles that are identical. Genetic bottlenecks often go hand in hand with inbreeding. But recessive alleles can then be exposed to the population and then be by descent. Many organisms occupy ranges that are discontinuous purged out through selection. Population structure: how populations are found/distributed in space. They are found in rocky mountain areas. Can"t stay in a valley area too long before migrating to another higher mountain. Each population is constrained to a small geographic area. No subdivision: large inbreeding with each other. Extreme sd: populations have a large species range.
