Question

A small genetic change such as a single mutation may result in _____.

Answer 1

The correct answer is option B (Microevolution)

Microevolution is defined as a change is allele frequencies observed within a population. In contrast to macroevolution it can be observed within a short period of time even within a same generation.

Microevolution can occur due to following reasons:

- Gene flow or Gene migration

- Genetic drift

- Mutation

Answer 2

Answer:

The correct answer is microevolution.

Explanation:

Microevolution happens when there is a variation in the percentage of gene changes inside a set of inhabitants.

As its name tells us, microevolution happens in a short period of time and may simply be due to the fact that due to natural causes certain genes became stronger and more resistant from one generation to the other, or because within that population there was someone new who brought said improved gene. Other factors that can influence this small genetic change may be migration, genetic drift or a single mutation.

Therefore the answer to the given question is Microevolution.
