Vedclass · Answer

(D) Meiosis-$I$ is a reductional division where homologous chromosomes separate,reducing the chromosome number to half. However,each chromosome still consists of two sister chromatids (replicated $DNA$). Meiosis-$II$ is an equational division similar to mitosis,which is necessary to separate these sister chromatids so that each daughter cell receives a single chromatid (a complete set of unreplicated chromosomes).

When the number of chromosomes is already reduced to half in the first reductional division of meiosis,what is the necessity of the second meiotic division?
