Regarding Meiosis, which of the statement(s) is incorrect?
Answer: (B) DNA replication occurs in S phase of Meiosis-II. Answer: DNA replication occurs in S phase of Meiosis-II Solution: This is the incorrect statement: meiosis involves only a single cycle of DNA replication, which occurs in the S phase before meiosis I; there is no DNA replication (no S phase) before meiosis II.
- A.There are two stages in Meiosis, Meiosis-I and II
- B.DNA replication occurs in S phase of Meiosis-II✓
- C.Pairing of homologous chromosomes and recombination occurs in Meiosis-I
- D.Four haploid cells are formed at the end of Meiosis-II
Correct Answer
(B) DNA replication occurs in S phase of Meiosis-II
Solution & Explanation
Answer: DNA replication occurs in S phase of Meiosis-II Solution: This is the incorrect statement: meiosis involves only a single cycle of DNA replication, which occurs in the S phase before meiosis I; there is no DNA replication (no S phase) before meiosis II. The other statements are correct — meiosis has two stages (I and II), homologous pairing and recombination occur in meiosis I, and four haploid cells result at the end of meiosis II.
