Question

What term is defined as the change in allele frequencies that occurs when a new population is established?

Answer 1

Answer: Genetic drift

Explanation: Genetic drift is the change in allele frequencies that occurs when a new population is established. It is one of the major cause of the evolution of new species. Genetic drift is accompanied by a change in allele frequencies, the effects of genetic drift is always intense in smaller population compared to that of a larger one.

Answer 2

Genetic Drift

Step-by-step explanation:

Allele frequency is the measure of incidence of a gene variant in population and it is usually expressed as a percentage or a proportion.

Genetic drift is a mechanism of evolution caused by a change in allele frequencies due to establishment of a new population.

There are two ways it can occur bottle neck and the founders effect.

Bottle-neck is when a population becomes very small very quickly where as Founder effect is when a population colonizes a new location.
