Population Genetics

The theory of population genetics and how evolution occurs includes all but which of the following

• Mating must be random

• The size of the population is small

• There is no influx of genes from other population

• No genotype has selective advantage over another

Random mating is defined as

• members of a population choose to mate with individuals of a particular phenotype

• members of a population choose to mate with unrelated individuals

• members of the population mate with each other without regard to their phenotypes or genotypes

• members of a population choose to mate with closely related individuals

When a gene pool of a population changed, it means ...

• number of organims in the population changes

• organisms in the population are breeding randomly

• the population is in genetic equilibrium

• the population is undergoing evolution

What does it mean when a population is in genetic equilibrium?

• a small population that doesn't have genetic drift

• a large population that doesn't have genetic drift

• a small population that does have genetic drift

• a large population that does have genetic drift

The population is in genetic equilibrium if

• No random mating

• Natural selection occurs

• The population size is small

• No migration

p+q = 1

p is

• Frequency of dominant phenotype

• Frequency of dominant genotype

• Frequency of dominant allele

• Frequency of recessive allele

• p² + 2pq

• p + p²

• 2pq + q²

• 2pq
