Lub cell yog nyob rau hauv metaphase II thaum cov chromosomes dlhos lawv tus kheej raws cov metaphase phaj los ntawm kev yooj yim ntawm cov spindle fibers. Cov spindle fibers tam sim no txuas rau ob lub kinetochores uas muaj nyob rau hauv centromere ntawm txhua chromosome.
metaphase 2 meiosis yog dab tsi?
Metaphase II: Tus khub chromosomes kab. Anaphase II: Cov chromatids sib cais ntawm lub centromere thiab tsiv raws cov spindle fibers rau cov ncej. Telophase II: Cov hlwb pinch hauv nruab nrab thiab faib dua. Qhov kawg tshwm sim yog plaub lub hlwb, txhua tus muaj ib nrab ntawm cov khoom siv caj ces pom nyob rau hauv thawj.
Yuav ua li cas ntawm metaphase II?
Thaum lub sijhawm metaphase II, cov chromosomes dlhos raws lub cell's equatorial phaj. Thaum lub sij hawm metaphase II, cov chromosomes ua raws li cov cell's equatorial phaj.
Puas metaphase 1 zoo ib yam li metaphase 2?
Metaphase 1 yog txuam nrog meiosis 1 whereas metaphase 2 yog txuam nrog meiosis 2. Qhov sib txawv tseem ceeb ntawm metaphase 1 thiab 2 yog cov chromosomes txuas ua homologous khub ntawm txoj kab nruab nrab thaum lub sij hawm metaphase 1 thiab thaum metaphase 2, ib chromosomes txuas rau ntawm kab zauv.
Dab tsi yog qhov tseem ceeb ntawm metaphase 2?
Metaphase II hauv Meiosis
Ntawm no yog theem uas ob tus ntxhais cell tsim thaum thawj zaug meiotic division, muaj lawv cov meiotic spindles pib kos cov chromosomes rau metaphase phaj,dua. Qhov no yog los npaj lub centrosome rau kev faib nyob rau theem tom ntej.
