)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?

Question
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?
