. Assertion:Reduction division occurs in anaphase-I. So there is no need of meiosis


Reason: Meiosis-II occurs to separate homologous chromosomes

Best Answer

Answer ||| d

Solution ||| Anaphase-I involves separation of homologous chromosomes into different daughter cells. So, meiosis I is a reductional division. But each chromosome is still formed of two sister chromatids joined at the common centromere. Anaphase-I results in reduction in number of chromosomes but ech chromosome has double amount of DNA, so meiosis Ii occurs, during, which chromatids of each chromosome separate into different cells. Main aim of meiosis II is to separate genetically modified chromatids of each homologous chromosome formed during crossing over in meiosis-I.
