Population genetics focuses on:
Correct answer: C. Quantitative traits
- A. Qualitative traits
- B. Inherited traits
- C. Quantitative traits
- D. None of these
Explanation
Population genetics is concerned with the study of how gene frequencies in a population change over time, particularly focusing on quantitative traits which are influenced by multiple genes. These traits provide valuable insights into the evolutionary process. While inherited traits are part of the study, the emphasis is on quantitative traits for understanding genetic variation and evolution. Qualitative traits and the option 'None of these' do not accurately represent the primary focus of population genetics.

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.
