Two populations of the same species of fish have been isolated in different lakes for hundreds of years. during a flood event, a permanent stream forms between the two lakes, allowing fish to move back and forth. how will this affect allele frequencies in the two populations?

The Allele frequencies in the fish population will become more similar over time.

Explanation: The Allele frequency also known as the gene frequency, is the relative frequency of an allele (which is a variant of a gene) at a particular section in a population, normally expressed as a fraction or percentage.

To be more precise , it is the fraction of all chromosomes in the population that carry that gene.

If during a flood event a permanent stream forms between two lakes allowing fishes to move back and forth, it would cause the allele frequencies in the fish population to become more similar.
