Answer:
d
Explanation:
<em>Crossing over shuffles alleles on non-sister chromatids of homologous chromosomes.</em>
At the prophase I stage of meiosis, homologous chromosomes synapsed to form a four-chromatid structure known as tetrad. Exchange of chromosomal segments between non-sister chromatids of the tetrad then takes place, a process that results in the reshuffling of genes or alleles on the non-sister chromatids.
Hence, none of the answers is correct.
Correct option: d
A.
Let's break it down:
-If the study has been conducted by multiple others and they get different results, it might be a sign that something went wrong in the experiment, and the data is unreliable. For example, if everybody else timed an event and got the same exact time except for the fact that you got a different time, you may start to suspect that you had done something wrong and the data was unusable.

An example of refraction<span> is when </span>waves<span> approach a straight shoreline at an angle. The part of the </span>wave<span> crest closer to shore is in shallower water and moving slower than the part away from the shore in deeper water. The </span>wave<span> crest in deeper water catches up so that the </span>wave<span> crest tends to become parallel to the shore.</span>
