The best way is to compare the DNA of the two species. The more nitrogenous bases and amino acids two species have in common, the more closely related they are.
Crossing over is the main event in meiosis and heredity as it leads to genetic variation.
<h3>What is genetic variation?</h3>

Thus, it can be concluded that crossing over between non-sister chromatids during meiosis is significant in heredity as it leads to genetic variation.
