3. 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.

I would expect to see a greater variety of traits observed. Simplistically, I would expect to see people with blue eyes and brown hair, blonde hair or red hair. Whereas in a population where chromosomes do not cross over, I would expect to see traits that are more frequently associated with each other. For example, I would expect to see a greater proportion of blue eyed people to be blonde because the gene for hair colour is more frequently associated with the gene for eye colour.

Answer: The population that has experience of cross over will have greater genetic variation as compared to the population who has not gone through cross over.

Explanation:

The population of the species that has crossed over will have recombination which shows different traits. Every time the cross over takes place new recombination can be seen which adds genetic variation and diversity to the populations. This variation in the characters increases the chances of this population to survive.

The population that has no cross over has no genetic variation among the individuals in a population. They can all die at the same time in case of harsh conditions as all the individuals are same and have no genetic diversity.
