Two species of fish had recently undergone sympatric speciation. The males of each species had a different coloring through which females could identify and choose a partner from her own species. After some time, pollution made the lake so cloudy it was hard for females to distinguish colors. What might take place in this situation?
Which of the following is a factor that, by itself, does not promotewidespread changes in allele or genotype frequencies?a. New mutationb. Natural selectionc. Genetic driftd. Migratione. Nonrandom mating
Deer mice are usually found mice that live in the Sand Hills of Nebraska, however, have evolved a lighter coloring, the result of a change in one gene. The initial population of deer mice in the Sand Hills was probably dark brown, like all other deer mice. What was the driving force behind the evolution of this population?* the woods and are dark brown in color. The deer O Mutation O Speciation O Equilibrium O Predation

Genetic drift and natural selection can both result in rapid evolution. However, O A. natural selection requires genetic drift to provide new variation in populations. O B. genetic drift works slowly in small populations. O C, only drift leads to adaptation. O D. both processes of evolution could be slowed by gene flow.
Although the individuals in a population must differ genetically for evolution to occur, the presence of genetic variation does not guarantee that a population will evolve. For that to happen, one or more factors that cause evolution must be at work. Which of the following is NOT the causes of microevolution?

It is likely that, ancestrally, pocket mice were light colored. The dark coloration evolved recently in populations on the young, dark lava flows. For the evolution of dark pocket mice to occur, there must have been A. some individuals in the ancestral population that had mutations that made them darker than other individuals B. a large population of dark pocket mice somewhere in the species range in the ancestral population nC. a mutation that turned all light colored mice into dark colored mice at once N D. a gradual darkening of light colored mice during their lifetime so that they could occupy the dark lava flow
