The correct answer is option D, that is, large genetic diversity.
The total number of genetic features in the genetic makeup of a species is known as genetic diversity. It is different from genetic variability, which illustrates the capacity of the genetic features to differ.
Genetic diversity can be a result of mutation, random fertilization, random mating, and recombination among the homologous chromosomes at the time of meiosis. It functions as a way for the populations to amend with the modifying environments. Therefore, it should not result in the decline of a population.
