WebWhy is there no DNA replication in meiosis 2? First thing to remember is that interphase is a stage associated with replication of DNA, and growth. Once meiosis starts, the purpose is to produce a haploid gamete. So there is no further need of replication or growth. Hence between meiosis I and meiosis II , there is no interphase. iron group s.a cuit
