Do you think gene flow in the human population is more or less common in the twenty-first century? Explain your answer.

Gene flow is an important mechanism for transferring genetic diversity among populations. Migrants change the distribution of genetic diversity within the populations, by modifying the allele frequencies (the proportion of members carrying a particular variant of a gene).

Explanation:

Gene flow includes lots of different kinds of events, such as pollen being blown to a new destination or people moving to new cities or countries. If gene versions are carried to a population where those gene versions previously did not exist, gene flow can be a very important source of genetic variation.Gene flow is important because even low levels of gene flow can have a large impact, counteracting the other evolutionary forces. So what is gene flow? It's the movement of alleles from one population to another.
