Question

The factors responsible for species isolation are-

• A. Gene flow
• B. Genetic drift
• C. Both (a) and (b)
• D. Adaptation

Answer 1

The correct option is C Both (a) and (b)

Gene flow is also called gene migration, that means; the introduction of genetic material from one population of species to another. Genetic drift is a change in allele frequencies within a population over time. It is the random fluctuations in the number of gene variants in a population.
