SpletWhich is the longest phase in oogenesis in female? diplotene stage of prophase I The longest phase in oogenesis is the diplotene stage of prophase I, where the first meiotic division gets arrested in the primary oocytes. How many eggs are produced in oogenesis? one egg In human females, the process that produces mature eggs is called oogenesis. SpletThe prophase is the longest meiotic phase, therefore, for the sake of convenience, it is divided into six sub stages, viz., preleptonema (proleptotene), leptonema (leptotene), zygonema (zygotene), pachynema (pachytene), diplonema (diplotene) and diakinesis. The successive meiotic sub stages can be represented as follows: SpletFormation. The formation of a bivalent occurs during the first division of meiosis (in the pachynema stage of meiotic prophase 1). In most organisms, each replicated chromosome (composed of two identical sister chromatids) elicits formation of DNA double-strand breaks during the leptotene phase. google office editing for docs
