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:
Animals are made up of eukaryotic cells, meaning they have a nucleus which contains the DNA. :)
Ocean tides are caused by the gravitation of the Moon. Currents can be
formed by the flow of tidal water around the continental plates, or by a
difference in water temperature between large ocean areas. Surface
waves are caused by the wind. Abnormal waves can be created by the
tectonic movement of plates around and under the ocean floor (tsunamis).
So as you can see, the answer is (C) Gravity
