Expert Solution

Step 1

There can be various reasons for egg not being hatched.

A. Genetic drift occurs in low population areas in this the population faces different natural calamities which decreases the number of individual in a population and it also causes the harmful gene to be fixed into that population.

Since the cause for not hatching the egg can be increase in temperature, or due to poor reproduction or may be due to effect in certain genes
