Question

How might the allele frequencies change if a new bonobo population moved into the area and gene flow occurred between the fifth generation and newly-arrived bonobos?

Answer 1

Gene flow is one of the mechanisms that can change the frequencies of alleles by transfer the genes from the gene pool of one population to another. Newly-arrived bonobos will bring the gametes that can reproduce. So, the introduction of new alleles will increase the variability within a population and will allow the new combinations of traits.
