Web12 jan. 2016 · Prophase 1 of meiosis is where the crossing-over occur. Explanation: Each of the homologous chromosome line up side by side, forming tetrads. While they lined up, segments of the chromosomes may be exchanged. This process is important as it promotes genetic diversity.
WebAlthough in many cases the chromosomes do undergo some dispersion, they do not reach the extremely extended state of the interphase nucleus. The stage between the two meiotic divisions is called interkinesis and is generally short lived. Interkinesis is followed by prophase II, a much simpler prophase than prophase I. 10.4 Meiosis II Web10 jun. 2013 · Tetrads form so that chromosomes can undergo crossing over which is a form of genetic recombination.
