Question

You are researching a population of moles. In the course of your research, you identify a nearby population that occasionally comes into contact with your study population.

What best describes the evolutionary process at work?

A. Mutation
B. Natural selection
C. Artificial selection
D. Gene flow
E. Genetic drift

Answer 1

Option D, Gene Flow

Step-by-step explanation:

Gene flow is defined as the flow of genes from one population to other thereby causing variation in the base population. Here the population of mole will have a certain number of genes but its interaction with a foreign species will lead to evolution of population through natural selection and genes of this foreign species will also get mixed with genes of mole population which later on may lead to further variations with in a single set of population inclusive of all .

Hence, option D is correct
