MCQ on Population Genetics with Answers (PDF)

Population genetics is the study of the genetic composition of populations and how it changes over time due to evolutionary processes such as mutation, natural selection, genetic drift, and gene flow. It combines principles from genetics, statistics, and evolutionary biology to understand how alleles are distributed in populations and how these distributions affect traits and species evolution. Population genetics provides insight into the mechanisms of evolutionary change at the genetic level. This is an MCQ on Population Genetics with Answers.
