Question

Explain the relationship between crossing over
and genetic variation.

Answer 1

Crossing over results in new combinations of alleles. Combinations that can result in new phenotypes or increased variety types of phenotypes. This way there increased genotype variation but the actual genes are still the same

Answer 2

There is direct relationship between genetic variation and crossing over.

Explanation: Crossing over is the main cause of genetic variation because in crossing over, parts of chromosomes are exchanged between two different chromatids in the process of gametes production. These chromatids are different from the parent chromosomes so variation occurs in the genetic makeup of living organisms due to crossing over.
