1. You measure the effects of a single allele (A2) on fitness in two populations of the same plant species, Population X and Population Y. Population X lives at higher altitudes. The average excess of fitness of the A2 allele (aA2) in Population X is 1.21, and the average fitness of the population (w) is 1.0. Population Y lives at a lower altitude. The average excess of fitness of the A2 allele (aA2) in Population Y is -1.68 and the average fitness of the population (w) is 1.0 a) Which population is likely to experience faster evolution? Why? b) What do you predict will happen to the frequency of the A2 allele (pA2) in population X? c) What do you predict will happen to the frequency of the A2 allele (pA2) in population Y? d) Why do you think the average excess of fitness of the A2 allele is different in these two populations?

A dog breeder thinks that he will be able to charge higher prices for extra-tiny versions ofsmall dogs. He starts off by trying to selectively breed smaller Yorkshire terriers. The averageadult mass of the terriers in his kennel is 2.5 kg. He selects a subset of the smallest dogs to foundhis new tiny dog line. The average mass of the 20 selected dogs is 1.8 kg. He chooses matedpairs randomly from that pool of 20 dogs and rears the resulting puppies to adulthood. Theaverage mass of these offspring was 2.4 kg. Disappointed with the results, the breeder wantsyour help in figuring out where his plan went wrong. 5a.What is the narrow-sense heritability of body size in his population of dogs? 5b. You examine his records and calculate the total phenotypic variance VP across his wholestarting population of yorkies to be 1.1. What is the additive genetic variance VA in thispopulation? 5c. The breeder clearly kept very good records of dog size measurements across the pedigrees inhis…
3) Movement of alleles between populations is called _____ and results in _____. a.genetic equilibrium; decreased genetic differences between populations b.genetic drift; increased genetic differences between the populations c.gene flow; increased genetic differences between the populations d.genetic drift; decreased genetic differences between the populations e.gene flow; decreased genetic differences between the populations
2) The more impressive the tail of a male peacock, the higher its chances of finding a mate. Female peacocks choose mates based on the color of the feathers and the overall physical prowess of the animal. However, a genetic mutation called leucism can produce a peacock with only white feathers. This mutation causes the inability of pigment to be deposited into their feathers which results in a white appearance. What would you infer to be the fitness of the white peacock? Choose ALL that apply. A) The females will equally choose the brightly colored and white peacocks as mates. Eliminate B) White peacocks are highly prized, thought to symbolize purity, eternity, and unconditional love, making them desirable mates. C) If females choose the brightest males as partners, the ones without the impressive tails will be less likely to mate and reproduce. D) White peacocks are highly prized, thought to symbolize purity, eternity, and unconditional love, causing them to…
