NEET Previous Year Question
Which is incorrect statement about meiosis?
Topic: NEET PYQ
Answer: C. Full step-by-step solution below.
- AMeiosis involves two sequential cycles of nuclear and cell division called meiosis I and meiosis II but only a single cycle of DNA replication.
- BMeiosis I is initiated after parental chromosome have replicated to produce sister chromatids at the S phase.
- CMeiosis involves pairing of nonhomologous chromosomes and recombination between them.
- DFour haploid cells are formed at the end of meiosis-II.
Correct answer: C
Solution
(c) because meiosis involves pairing of homologous chromosomes, not non-homologous chromosomes. Crossing over/recombination also occurs between non-sister chromatids of homologous chromosomes during pachytene of Prophase-I.More Cell Cycle & Cell Division PYQs
