Which principle helps in determining the ratio of a phenotype in a population?
Correct answer: C. Hardy-Weinberg's principle
- A. Darwin's natural selection
- B. Lamarck's theory
- C. Hardy-Weinberg's principle
- D. None of these options are correct
Explanation
Option A: Darwin suggested that populations of individual species become better adapted to their environments through natural selection, thus this is not the correct option.Option B: Lamarck suggested that physical changes in organisms during their lifetime could be transmitted to their offsprings, this is not the correct option.Option C: This states that allele in a population will remain constant from generation to generation in the absence of other evolutionary influences, this is the correct option.Option D: As Option C is correct this can't be the correct option.

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.
