Answer 3

Let me say the Outline of the formation of chiasmata in the process of crossing over .
1) Neighboring non-sister chromatids are cut at the same point, a Holliday junction forms as the DNA of the cut sections attach to the open end of the opposite non-sister chromatid
2) As a result, alleles are swapped between non-sister chromatids increasing genetic variation through recombination of linked alleles
3) Crossing over is more likely to occur between genes which are further apart
@kimie15...reading this whats your answer?

Answer 4

crossing over is the exchange of genetic material between homologous chromosomes (non-sister chromosomes) that results in recombinant chromosomes.
