WebSolution. Verified by Toppr. Meiosis-1 is preceded by interphase in which DNA is replicated. Meiosis-1 begins with a long prophase. During prophase-1 the two homologs are joined together held by a synaptonemal complex of proteins. This forms a tetrad which consists of two homologous chromosomes with two sister chromatids.
