The answer is; A.
If r allele is found in 15% of the population, then the frequency of the allele is;
r = 15/100 = 0.15
Remember the equaition p + q = 1
Therefore; R + r = 1; R + 0.15 = 1; R = 1-0.15 = 0.85
RR = 0.85*0.85 = 0.7225
In percentage = 0.7225*100 = 72.25
Answer:
B
Explanation:
Directional selection tends to evolve towards one specific trait. In this example, white rabbits no longer have a competitive advantage because of disappearing snow. This means they are more easily spotted by predators, resulting in reduced fitness and less chance they will live to reproductive age and pass their recessive white alleles on.
Natural selection will favor the gray colour allele, increasing the frequency oft this previously rare allele.
