So this gamut will contain a slightly different genetic information slightly different chromosome than this one right here. But if no crossing overtook place, we would form two identical chromosomes lowercase B, lowercase V and lowercase B, lowercase V. Instead, because we do have crossing over that takes place, we form one lowercase B, one lowercase V, and the other one is uppercase B, lowercase V. So this is exactly what we mean by the process of crossing over. So we see that crossing over allows deploy organisms, such as human beings to basically produce these sex cells, these gamings that have slightly different genetic information than the actual parent, than the parent, or than the female or the male parent. Because, remember, this chromosome came from the male parent and this chromosome came from the female parent. If no genetic recombination in the form of crossing over took place, then the gamuts that we would form at the end, these gamuts here, would be exactly identical to the gametes that came from the parents, the male and the female. But because of crossing over, we form these gametes that are slightly different.
