Notes of metaphase ii of meiosis
WebOct 27, 2024 · Definition. Prophase I of meiosis I is a process that involves five different stages during which genetic material in the form of alleles crosses over and recombines to form non-identical haploid chromatids. Prophase I is the first stage of meiosis I, followed by prophase II, anaphase I, anaphase II, metaphase I and metaphase II. WebNote: Metaphase II of meiosis can be differentiated from metaphase-I on the basis of the following features: (ii) Each chromosome of metaphase II has two chromatid (Fig. 7.3a) whereas in metaphase I these are paired homologous chromosomes each having two chromatids thus forming tetrad. (iii) In the metaphase I of meiosis, a few chiasmata are ...

WebAt metaphase II, the sister chromatids are arranged at the metaphase plate. Because of crossing over in meiosis I, the two sister chromatids of each chromosome are no longer genetically identical. The kinetochores of sister chromatids attach to microtubules extending from opposite poles. WebMeiosis-I: The first meiotic division consists of four stages-Prophase I, Metaphase I, Anaphase I and Telophase I (Fig. 5.3B). Prophase I: Meiosis I has a long drawn out prophase which is divided into five sub-phases, namely, leptotene, zygotene, pachytene, diplotene and diakinesis. Leptotene:
