Which one of the following explains Hardy-Weinberg's principle?
Options
- AIn nature, a given habitat has enough resources to support a maximum possible number called carrying capacity.
- BThe allele frequency and genotypic frequency remain constant from generation to generation.
- CThe species richness increases with the increase in area but to a certain limit.
- DLoss of key species will certainly cause a threat in a very short span of time.
Correct answer
B. The allele frequency and genotypic frequency remain constant from generation to generation.
Step-by-step solution
The Hardy-Weinberg principle states that allele frequencies in a population are stable and remain constant from generation to generation in the absence of evolutionary influences. The gene pool (total genes and their alleles in a population) remains constant, which is called genetic equilibrium. The statement regarding carrying capacity is related to logistic population growth. The statement regarding species richness and area is the species-area relationship proposed by Alexander von Humboldt. The statement regard
