What genetic factor is most likely to result in the extinction of an entire species?

a lack of genetic variety in the population

Explanation:

A population needs a lot of genetic variability in order to survive changes in environmental conditions.

A lack of genetic variety puts a population at risk. For example, if an entire species lacks resistance to a disease and that disease becomes a problem in the species' habitat, the entire species could become extinct.

it is a part of john locke's natural rights popular during the age of enlightenment that people had inalienable rights to life, liberty and property. this was reflected by thomas jefferson in his declaration of independence as rights to life,liberty and the pursuit of happiness.

another line in the declaration of independence is that people have certain rights just because they are human. humans are capable of obeying the three natural rights john locke mentioned making them governable by these laws and therefore entitled to these rights as well.
