WebMay 14, 2024 · The first cleavage occurs shortly after the zygote nucleus forms. A furrow appears that runs longitudinally through the poles of the egg, passing through the point at which the sperm entered and bisecting the gray crescent. This divides the egg into two halves forming the 2-cell stage. The second cleavage forms the 4-cell stage. WebThis is called homolytic cleavage or homolysis. The electron pair separates evenly to each part, and as a result both products contain a single electron. The species that contains one or more single electron is called a radical (or free radical). Radicals are produced from homolytic cleavage.
