Explanation:
The Population growth rate is a change in population with time taken into consideration. It can be expressed with the formula
where N is the total change in the population size, and t is time.
When immigration and emigration are factored in, we now have the formula;
Answer:
A genetic drift is defines as the change in the allele frequency of an existing population. It arises as a result of random variation in a population. The rate of genetic drift would be greatest in a small population that are geographically isolated from the parent population. A change in the allele frequency of a population as a result of chance rather than the natural selection.
