Correct answer: A. Population genetics
- A. Population genetics
- B. Molecular biology
- C. Embryology
- D. Cytogenetics
Explanation
Population genetics is the study of genetic variation within and among populations and the evolutionary factors that explain this variation. Its foundation is the Hardy - Weinberg law, which is maintained as long as population size is large, mating is at random, and mutation, selection and migration are negligible.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
