검증된 단계별 안내1
Understand the overall process of meiosis, which consists of two sequential divisions: Meiosis I and Meiosis II.
Recall that DNA replication occurs before meiosis begins, during the S phase of interphase, not during Meiosis I itself.
Identify that Meiosis I is called the reductional division because it reduces the chromosome number by separating homologous chromosomes into different daughter cells.
Recognize that sister chromatids remain attached during Meiosis I and are only separated during Meiosis II.
Note that Meiosis I results in two haploid cells, not four; the four haploid cells are produced after Meiosis II is complete.
