Answer:
Genetic diversity
Step-by-step explanation:
Genetic diversity is when a population of a species, humans, in this case, have different genes between different individuals. One person may have blue eyes while the others have brown. This shows diversity within the gene pool.
Genetic diversity is also important to the survival of a species. Two-parent reproduction leads to genetic diversity. Having different alleles within a population allows for adaptation. On the other hand, one-parent reproduction does not allow for genetic diversity. This hinders the species because it does not let species to slowly improve the gene pool through natural selection and adaptation.
