WebJun 3, 2024 · Multiple events occur during prophase I to allow the interaction between homologs and the formation of at least one crossing over (CO) per homolog pair, by homologous recombination. At the DNA level, exchanges are highly regulated in time, space, and choice of recombination partner. Web1) DNA should have replicated before meiosis 2) Inorder for crossing over in meiosis I of prophase I to occur, 99.7% of DNA replication and 75% of histone synthesis must occur by prophase I. The key points are The number of chromosomes=count the number of centromeres The number of DNA molecule = count the number of chromatids

WebThe formation of a bivalent occurs during the first division of meiosis (in the zygotene stage of meiotic prophase 1). In most organisms, each replicated chromosome (composed of two identical sister chromatids [1] [2]) elicits formation of DNA double-strand breaks during the leptotene phase. [3]
WebApr 11, 2024 · Complete answer: In meiosis I or reductional division, prophase I is divided into five stages: leptotene, zygotene, pachytene, diplotene, and diakinesis.
