Meiosis cell division byjus
WebThe two phases of meiosis are meiosis I and meiosis II. Meiosis I is when the chromosome number reduces (from diploid to haploid), while during the meiosis II phase, the chromosome number is maintained in the daughter cell, which is haploid. DNA replication only occurs prior to meiosis I during the interphase I stage. WebNCERT Solutions for Class 10 English - Learn CBSE.
