Is meiosis DNA replication?

No, meiosis is not DNA replication itself, but it is a process that involves DNA replication. DNA replication occurs before meiosis starts, during the S phase of the cell cycle, which is part of interphase. After replication, meiosis proceeds through two rounds of division—meiosis I and meiosis II—which reduce the chromosome number by half, producing four non-identical haploid cells. DNA replication ensures that the genetic material is copied before meiosis begins, allowing for genetic diversity in the resulting gametes (sperm or eggs).
