The situation in which allele frequency in the gene pool of a population remain constant is called
a. evolution
b. genetic drift
c. genetic equilibrium
d. natural selection

The correct answer is -

c. genetic equilibrium.

Genetic equilibrium can be described as a condition when gene variant or genotype of a population does not change from generation to generation. In other words, the frequency of gene variant (also called allele) in a gene pool is constant.

It occurs when there is no evolutionary force (like genetic drift, natural selection) acting upn the population, suggesting that no evolution is going on as the allele frequencies are constant.

Thus, option c) is the right answer.

lysosomes contain a variety of enzymes, enabling the cell to break down various biomolecules it engulfs, including peptides, nucleic acids, carbohydrates, and lipids (lysosomal lipase). the enzymes responsible for this hydrolysis require an acidic environment for optimal activity. hope i !
