Answer: Begins with haploid cells.
- A Pairs homologous chromosomes
- B Halves the chromosome number
- C Involves crossing over
- D Begins with haploid cells
Correct answer: D. Begins with haploid cells
Explanation: Meiosis II mechanically resembles mitosis (sister chromatids separate) but starts with the haploid cells produced by meiosis I.
The cell cycle: G1 (growth and preparation), S (DNA replication, chromosome number stays 2n but DNA content doubles), G2 (final checks before division), and M (mitosis itself) - together, G1+S+G2 make up interphase.
