Document Summary
Suppose that even female stinkbugs decide that males are too stinky; however, males with no smell are preferred bird food. Stabilizing selection (two extremes are being taken out) If the population is reduced drastically the allele frequencies may change - not as a result of selection. Many species that have been reduced to small numbers (and then recover) Very little genetic variability in the wild due to the bottleneck. Population recovered well though genetics different after bottleneck. Start a new population with a small subset of the original population. Achromatopsia (pingalap, population in south pacific: sacks. However, it introduces new alleles into populations that may not have arisen through mutation. Week 3 page 1 have arisen through mutation. Ecologically, responsible for insecticide resistance in mosquito populations. Depend on climate (temp and precipitation) - vary with latitude (and altitude) Plants (and animals) have adaptations that enable them to live in certain conditions.
