Question

What causes many endangered species that are now found only in zoos to have very little genetic variation?

Answer 1

Poaching and destruction of natural habitats.

Excessive poaching and destruction of the ntural habitats of the organisms lead to the decrease in the genetic variations and finally extinction. In that situation, the organisms are confined to the zoos. This type of organisms are called as edangered i.e., that organisms require special protection. Lack of proper plans, they may extinct.
