What differences would you expect to see in a population made up of individuals whose chromosomes experience crossing-over frequently compared with a population made up of individuals whose chromosomes do not cross over? explain your reasoning.

For the answer to the question above asking what differences would you expect to see in a population made up of individuals whose chromosomes experience crossing-over frequently compared with a population made up of individuals whose chromosomes do not cross over? My answer is that I'd expect a larger gene pool and more diversity in the population whose chromosomes frequently cross-over or much more genetic variability. 
for example different phenotypes are most likely exhibited.
