Natural selection is the differential reproduction of genotypes. It is measured as fitness, which is the reproductive success of a genotype compared with other genotypes in a population.
-The average numbers of offspring produced by three genotypes are: GG = 6; Gg = 3, gg = 2. What is the fitness of Gg?
A) 3
B) 0.5
C) 0.3
D) 0.27

Question

Quizplus · Accepted Answer

Fitness is calculated by dividing the average number of offspring of the genotype by the highest average number of offspring among the genotypes. For Gg, fitness = 3/6 = 0.5.
