Crossing Over

Vedclass · Answer

(C) Genetic variation in sexually reproducing organisms is primarily caused by the process of $Crossing 	ext{ } Over$. During meiosis, specifically in the $Pachytene$ stage of $Prophase-I$, homologous chromosomes exchange segments of genetic material. The frequency of $Crossing 	ext{ } Over$ is directly proportional to the distance between genes on a chromosome. Since longer chromosomes provide more physical space for these exchanges to occur, they facilitate a higher frequency of recombination, leading to increased genetic variation.

The greater the length of the chromosomes in an organism, the greater the genetic variation. This variation is obtained from which of the following processes?
