DARWIN’S THEORY OF NATURAL SELECTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The situation in which allele frequencies of a population remain constant is called
A
evolution
B
genetic drift
C
genetic equilibrium
D
natural selection
Explanation: 

Detailed explanation-1: -The equation is an expression of the principle known as Hardy-Weinberg equilibrium, which states that the amount of genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.

Detailed explanation-2: -Genetic equilibrium occurs when there is no evolution within the population. In other words, the frequency of alleles (variants of a gene) will be the same from one generation to another. At genetic equilibrium, the gene or allele frequencies are stable-they do not change.

Detailed explanation-3: -When allele frequencies remain constant it is called genetic equilibrium.

Detailed explanation-4: -The condition where a gene pool is not changing in frequency across generations is a genetic equilibrium. This is because the evolutionary forces acting upon the allele are equal. As a result, the population does not evolve even after several generations.

Detailed explanation-5: -Genetic equilibrium is the condition of an allele or genotype in a gene pool (such as a population) where the frequency does not change from generation to generation. Genetic equilibrium describes a theoretical state that is the basis for determining whether and in what ways populations may deviate from it.
