According to Hardy-Weinberg theorem, the sum of recessive homozygotes, dominant homozygotes, and heterozygotes is equal to 1, what is represented by 1?
Correct answer: A. Gene pool of the trait in the population
- A. Gene pool of the trait in the population
- B. Population density or total number of individuals in the population
- C. Tolal number of heterozygotes
- D. Total number of homozyotes
Explanation
The Hardy-Weinberg principle states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of evolutionary influences like mutation, migration, genetic drift, and natural selection .The Hardy-Weinberg genotype frequencies, p2 + 2pq + q2, represent the binomial expansion of (p + q)2, and also sum to one (as must the frequencies of all genotypes in any population, whether it is in Hardy-Weinberg equilibrium).

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.
