A population of snails lives in a large field. As the size of the population grows, individual organisms on one side of the field stop mating with individuals from the opposite side. Which of the following statements is true?

This is an example of an increase in gene flow.
Over time, genetic differences between individual snails will increase.
Over time, genetic differences between individual snails will decrease.
The snail population will eventually split in two and evolve side by side in cospeciation.

answer:

A) Over time, genetic differences between individual snails will increase

answer:

Alllopatric speciation.

Explanation:

This is the type of speciation in which organisms of the same species are separated from each other by geographical barrier (isolated) to the extent that the selective pressures in individual environment affected their gene flow.

Therefore , if the these organism mated when reunited,they will not be able to produce offspring.

It is also known as Geographical speciation. Therefore new species of organisms have emerged.

This is speciation.
