Microevolution

Step-by-step explanation:

It is a systematic change in allele (gene) frequency in a population of living organisms over a certain period of time. This change maybe caused by:

1. Mutation-A change in genetic composition of an organism due to environmental factors such as the excessive exposure of an organism to radiation.

2. Natural selection-Which occurs when some organisms have to survive a changing environment as a result of the possesion of some beneficial traits.

3. Gene flow-which involves the transfer of genes from one population to another.

4. Genetic drift-which is a difference or variation in the genetic make-up among organisms of the same species.
