Henry was studying two populations of the same species of lizards. One population lived on an island and the other lived on the mainland. Both populations were affected by a hurricane that hit the island and the mainland with equal force. A year later, Henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. Which best describes a conclusion he might have reached?

The answer is Genetic drift greatly affects small populations, but large populations can recover. Genetic drift is a change in an allele frequency in a population due to the random sampling of organisms. It usually occurs after some catastrophe, such as a hurricane. It usually affects small populations than large ones because in the large populations there are enough organisms that can counteract the changes in an allele frequency.

The conclusion Henry might have reached is genetic drift which greatly affects small populations than large populations.

What is Genetic drift?

Genetic drift is a change in an allele frequency in a population due to the random sampling of organisms.

Genetic drift can be caused by differential number of offspring in a given population.

The gene frequency can be affected by natural disaster such as Hurricane. It usually affects a small populations than a large population because large populations have enough organisms that can counteract the changes in an allele frequency.
