Which of the following types of non-random mating DOES result in evolutionary change on its own?   negative assortative mating   intrasexual selection   inbreeding   positive assortative mating

Which of the following is a TRUE statement?     Non-random mating will increase the number of heterozygotes.     Genetic drift within a population will increase genetic variation.     Migration into the population will decrease genetic variation.     Mutation will decrease genetic variation.     Stabilizing selection will increase genetic variation.

A population of fuzzy-wumpkins differ in how fuzzy their fur is. Populations in cold climates are fuzzier than in warm climates. Fuzzy-wumpkins mate for life.You transplant a reproductive pair of fuzzy-wumpkins from a warm climate into a cold climate, and a second pair from the cold climate into the warm climate. As a control you also transplant a reproductive pair from warm climate back to the warm climate and from the cold climate back to the cold climate. You then measure the fuzziness of the fur of offspring that were produced by each pair. Part A: If the fuzziness trait had a strong genetic component (e.g. high heritability) what pattern would you find between parent fuzziness and offspring fuzziness. (Figure A, B, or C based on image attached) Part B: The figure below presents the results of the transplant experiment. The x-axis shows the transplantation site for each reproductive pair. The y-axis shows the fuzziness of their offspring. The color in the bars shows the origin site…

There are two major mechanisms that help populations evolve. The first is Natural Selection. The second is Prezygotic Isolation Genetic Drift Directional Selection Independent Assortment
