Ob txoj kev faib, meiosis I thiab meiosis II, yuav tsum tsim gametes (Daim duab 3). Meiosis I yog ib qho kev faib ntawm tes tshwj xeeb uas tshwm sim hauv cov kab mob nkaus xwb; meiosis II zoo ib yam li kev faib mitotic.
Muaj pes tsawg qhov kev faib tshwm sim hauv mitosis thiab meiosis?
Mitosis cuam tshuam txog kev faib cell, whereas meiosis cuam tshuam nrog ob lub cell division.
Yuav muaj pes tsawg faib meiosis?
Meiosis muaj ob lub xov tooj sib cais faib , txhais tau tias ib tus niam txiv cell tuaj yeem tsim tau plaub gametes (qe in poj niam, phev in txiv neej). In txhua puag ncig ntawm division, cov hlwb mus txog plaub theem: prophase, metaphase, anaphase, thiab telophase.
Puas yog mitosis muaj 2 pawg?
Mitosis yog ib qho kev faib tawm nuclear uas ua rau ob lub nuclei, feem ntau muab faib ua ob lub hlwb tshiab.

Lawv muaj tib tus lej ntawm cov chromosomes: ib qho ntawm cov hlwb haploid, thiab ob qho ntawm cov hlwb diploid.
Puas yog ob txoj kev faib cell tshwm sim hauv mitosis lossis meiosis?
Cells faib thiab rov tsim dua ob txoj hauv kev, mitosis thiab meiosis. Mitosis ua rau ob lub hlwb zoo tib yam, thaum meiosis tshwm sim hauv plaub lub hlwb. Hauv qab no peb qhia txog qhov sib txawv ntawm cov yuam sij thiab qhov zoo sib xws ntawm ob hom kev faib ntawm tes.
