Meiosis where does it happen

Web24 mrt. 2011 · Meiosis occurs in the primordial germ cells, cells specified for sexual reproduction and separate from the body’s normal somatic cells. In preparation for meiosis, a germ cell goes through interphase, during which the entire cell (including the genetic material contained in the nucleus) undergoes replication. Web7 jul. 2024 · 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. Does Independent Assortment happen in meiosis 1 or meiosis 2? Homologous chromosomes separate in meiosis I. Sister chromatids separate in meiosis II.
