B) wBB = 100; wBb = 0.6; wbb = 0.01
C) wBB = 0.59; wBb = 0.35; wbb = 1.0
D) wB = 26; wb = 7

Quizplus · Accepted Answer

The relative fitness values for each genotype can be calculated by dividing the survival rate of each genotype by the survival rate of the genotype with the highest fitness. In this case, BB has the highest survival rate of 10/10 = 1.0, so the relative fitness values are:

wBB = 1.0/1.0 = 1.0
wBb = 6/10 = 0.6
wbb = 1/10 = 0.1

Therefore, the correct answer is A.
