Question

How does isolation of a population lead to a decrease in genetic diversity

Answer 1

Answer:

Decrease in genetic diversity reduces the chance of variation in the offspring.

Explanation:

If there is no variation, there will be no evolution. So, if there is a change in the environment (like an outbreak of a disease) that affects one of the organisms, it is likely to affect all of them and destroy the whole population. This would lead to extinction.
