Azombie apocalypse wipes out almost the entire human species before the zombie threat is eliminated. only a group of 100 people who were at a family reunion on an uninhabited island survived. they returned to the mainland completely unaware of what had happened to everyone. answer the following questions regarding the few survivors that now begin to rebuild the human population. despite an abundance of habitat, why will it be difficult for the human species to recover?

The correct answer would be - due to less or no genetic diversity.

Explanation:

The servived 100 people were from a single-family tree as it started in question so there will be very less or no genetic diversity in them. Genetic diversity is an essential process to adapt to the new diseases, infection or change into ecological condition.

This population of 100 people with almost the same gene may not adapt and would not be able to recover the human population.

Thus, the correct answer is - very low or no genetic diversity.

i believe the answer is a or 1
