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.

for many centuries there were important factors which the economies of the muslim empires developed increasingly. they applied economic procedures in production, investment, finance, taxation and property. they used to tax certain goods (for example: harvest), they charged interest on money lent, they signed contracts with merchants; they relied on a common currency, and they used checks as well as promissory notes. with the money collected by means of taxation, the government provided the needy with an income. in addition, trading networks covered huge distances, so far regions started to have contact and exchange goods. this trade network covered areas of asia, africa and europe.

the correct answer is c.
