Genetic equilibrium in a population refers to ..
constant allele frequencies in one generation to next generations
constant mutation rate in the population
equal numbers of dominant and recessive alleles
equal numbers of males and females
A gene pool consists of ..
all the alleles selected by natural selection
all the alleles present in a population
the entire genome of a sexually reproducing organism
the frequencies of the alleles for a gene locus within a population
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
