I know this sounds silly but I just took the test they were made in the stars or B
Answer:
A) all the genes that occur in the population.
Explanation:
The gene pool is defined as the set of all genes in population. The larger the genetic pool in population is, the grater genetic diversity is so the population can survive intense process of selection. On the other hand, low genetic diversity can cause reduced biological fitness and the chance of extinction is increased.
I would say the answer would be D.
Because: If a river is dammed then there is little to no flow going downstream. This will effect the life downstream and also change its conditions.
I Hope This Helped!
