Crossing over is the main event in meiosis and heredity as it leads to genetic variation.
<h3>What is genetic variation?</h3>
Genetic variation is the changes that take place in the genes of individuals that can lead to the formation of new characters.
it generally occurs in meiosis specifically during crossing over.
Thus, it can be concluded that crossing over between non-sister chromatids during meiosis is significant in heredity as it leads to genetic variation.

Answer:
I would say D.
Their conclusion only applies up until the 3rd plant, after that it seems to harm the growth.
Scientists use several methods to determine the proximity between species. Two of those methods may be an anatomical comparison, by examining the skeleton structure of two species, and DNA composition comparison, by comparison of genes, or specific parts of the DNA, that allow establishing the relative distance between species.
