multiple choice question\nwhich of the following is true of evolutionary forces in natural populations?\n\nevolutionary forces always increase the frequencies of new alleles in a natural population.\nevolutionary forces have no affect on allele frequencies in natural populations.\nevolutionary forces can alter allele frequencies in natural populations.\nevolutionary forces are responsible for having dominant and recessive alleles for most genes.

Answer

Brief Explanations:

Evolutionary forces such as mutation, natural selection, genetic drift, and gene - flow can change the frequencies of alleles in a natural population. They don't always increase new allele frequencies (mutation can introduce new alleles but selection may not favor them), they do affect allele frequencies, and dominant and recessive alleles are due to gene structure and function rather than solely evolutionary forces.

Answer:

Evolutionary forces can alter allele frequencies in natural populations.
