**Correct answer: A) bio-geographic isolation affects the random changes that take place within gene pools **
**The bio-geographic isolation of the species takes place when the geographical barrier work as a distinguishing agent. It takes place when the group of animals, plants and other creatures are not allowed to mate with each other. **
The mixing of there genes within the same species is separated by the geographical barrier.
The barrier allows the mating of the species in a different way as compared to the previous one.
Biogeographic isolation allows for the change of gene pools over time as (A) biogeographic isolation affects random changes that take place within the gene pool . ;
Biogeographic isolation limits gene flow between populations, allowing them to evolve independently. This results in natural selection, genetic drift, and the founder effect shaping distinct gene pools. Thus, the correct choice is B, as isolation affects which organisms breed and ultimately influences the gene pool change.
