Single Choice
Which of the following is not a characteristic of meiosis?
AIt involves two stages of DNA replication one before meiosis-I and another before meiosis-II.
Correct Answer
BIt involves recombination and crossing over.
CSister chromatids separate during anaphase-II.
DNuclear membrane disappears during prophase.
Solution
Chromosome replication occurs once but meiosis has two M-phase each with its own karyokinesis and cutokinesis. As a result chromosome number is halved. the transition period between M-phase I (meiosis I) and M-phase II (meiosis II) is short and without DNA replication. It is called interkinesis.
