Answer 1

A lack of genetic variety in the population is most likely to result in the extinction of an entire species. Having low genetic diversity makes a population more vulnerable to diseases, environmental changes, and other threats that could decimate the entire population. Without genetic variety, the population may not have the adaptability required to survive and thrive in changing conditions.
