The B аllele is dоminаnt tо the b аllele. If the percentage оf individuals with the BB or Bb genotype is very low, the fitness values of the BB or Bb genotypes are higher than the bb genotype. In contrast, when the percentage of individuals with the bb genotype is very low, the fitness of the bb genotype is the highest. Which pattern of selection does this represent?
