Question

Which genetic factor is most likely to result in the extinction of an entire species a lack of genetic diversity in the population a genetic defect in a few members of the population a genetic resistance against many diseases a lot of genetic variety in a population

Answer 1

A lack of genetic diversity in the population is most likely to result in the extinction of an entire species. This is because genetic diversity allows a population to adapt to changing environmental conditions and resist diseases. Without genetic diversity, a population may not have the necessary genetic traits to survive and reproduce. Additionally, genetic defects in a few members of the population or genetic resistance against many diseases may not necessarily result in extinction as long as there is enough genetic diversity in the population to maintain a viable population. A lot of genetic variety in a population can actually increase the chances of survival and adaptation in the face of challenges.
