Once genetic genetic isolation separates two populations from each other, genetic divergence begins to happen as a result of the processes of genetic drift, mutation, and natural selection. The process which is more likely to be the slowest is mutation.
<h3>What is mutation ?</h3>
A mutation is a change to an organism's DNA sequence. Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.
<h3>What is genetic drift ?</h3>
Genetic drift is an evolutionary process in which the frequency of a given gene allele varies randomly across a population.
<h3>What is natural selection ?</h3>
An evolutionary mechanism is natural selection. Environment-adapted organisms have a higher chance of surviving and dispersing the genes that contributed to their success. Over time, this mechanism leads to the evolution and divergence of species.
Thus from above conclusion we can say that once genetic genetic isolation separates two populations from each other, genetic divergence begins to happen as a result of the processes of genetic drift, mutation, and natural selection. The process which is more likely to be the slowest is mutation.
