Question

Assertion: Reduction division occurs in anaphase-I. So there is no need of meiosis.
Reason: Meiosis-II occurs to separate homologous chromosomes.
A. If both assertion `&` Reason are True `&` the Reason is a corrrect explanation of the Asserion.
B. If both Assertion `&` Reason are True but Reason is not correct explanation of the Assertion.
C. If Assertion is Trie but the Reason is False.
D. If both Assertion `&` Reason are false

Answer 1

Correct Answer - b
Anaphase-I involves separation of homologous chromosmes into different daughter cells. So, meiosis I is a reductional division. But eac h chromosome is still formed of two sister chromatids joined at the common centromers. Anaphase-I results in reduction in number of chromosmes but each chrosome has double amount of DNA so, meiosis -II occurs. during which chromatids of each chromsome separate genetically modified chromatids of each homologous chromosome formed during crossing over in meiosis-I.
