Question

Evolution is change in a population over time and includes the gene pools of that population. How does biogeographic isolation allow for the change of gene pools over time?

a Biogeographic isolation affects the random changes that take place within gene pools.

b Biogeographic isolation affects the changes in gene pools that result from which organisms are breeding.
c Biogeographic isolation determines who will win competition for mates.
d Biogeographic isolation determines the time that populations will breed.

Answer 1

Answer:

B

Explanation:

Biogeagraphical isolation leads to soeciation... Bcoz when they get isolated.. Face new environment get evolved and form new specie.. Having more potential.

Answer 2

a. Biogeographic isolation affects the random changes that take place within gene pools.

Explanation:

• All the genes including their allele in a population of a species is called gene pool. If a gene pool is large of a population than that population is considered to have rich genetic diversity.
• Bio geographic isolation allows the change in the gene pool because when a population separates geographically than they get a new environment.
• So to adapt in that environment they need to do random change in their gene pool so that they can get new genes or variations which help them to adapt to the new environment. So the right answer is a.
