A genetic study conducted over two generations found that the frequencies of genotypes in the first generation were AA: 0.36, Aa: 0.48, aa: 0.16. In the second generation, genotype frequencies remained the same. According to Hardy-Weinberg equilibrium, we can assume:

Random mating between the individuals of population.

Explanation:

Random mating refers to a condition in which all the members of a population have equal chances of mating with the opposite sex and is not prevented by any type of physical, psychological, biological, genetical and other barriers and the gene flows in the population.

In the given question, since the genotype of the population has not changed in the next generation, therefore, the population is following the assumptions of the Hardy Weinberg equilibrium in which the most important is that the individual is randomly mating with each other or show equal potency to mate with the opposite sex.

Thus, random mating is the correct answer.

affects the water bodies: excessive use of fertilizers causes eutrophication. the fertilizers which are used on plants affect the quality of land on which it is used, further causing erosion of soil. the fertilizers used on plants contain harmful chemical fumes which affect the environment.

only about ten percent of the energy at one trophic level is passed on to organisms at the next trophic level. the remainder of the energy is used in life processes or lost as heat.
