WebAlthough a cell needs to undergo interphase before entering meiosis, interphase is technically not part of meiosis. Crossing over occurs only during prophase I. http://www.actforlibraries.org/meiosis/
WebDuring what stage of meiosis is genetic variation increased? By meiosis II, only sister chromatids remain and homologous chromosomes have been moved to separate … WebThe initiation of meiosis requires both intrinsic and extrinsic signals. Meiosis is characterized by one round of DNA replication followed by two rounds of cell division, resulting in haploid germ cells. Crossing-over of DNA results in genetic exchange of genes between maternal and paternal DNA.
