A population has 0.01 BB individuals, 0.18 Bb and 0.81 bb
individuals. Assume 200 offspring are born, but only 50% of the bb
individuals make it to adulthood, the other genotypes fair just
fine. What is the frequency of the B allele in the next
generation?
Group of answer choices
0.716
0.03
0.01
0.83
Suppose a founding population has an allelic frequency not
typical of the original population. Which of the following effects
would most likely lead to homogenization?
Group of answer choices
no mutations within either population
genetic drift within the founding population
migration between the original and founding populations
random mating within the founding population
In Europe, there is a high frequency of the disease Muscular
Atrophy- even though there is reduced fitness of carriers. What
explanation is given for the maintenance of this polymorphism?
Group of answer choices
Mutation rate creating new alleles balanced with selection
against the allele is enough.
Heterosis, or heterozygote advantage.
Selection in the past has left some people that are immune to
the disease.
Migration of individuals from another population keeps
introducing the trait, even though there is selection against the
trait in Europe.
