Thaum telophase II , theem plaub ntawm meiosis II , cov chromosomes ncav cuag tus ncej, cytokinesis tshwm sim , ob lub hlwb tsim los ntawm meiosis kuv faib ua plaub lub hlwb haploid ntxhais, thiab lub hnab ntawv nuclear (dawb hauv daim duab ntawm txoj cai) daim ntawv.

Ntawm no, muaj pes tsawg chromosomes tom qab telophase 2?

1 Teb. Hauv tib neeg, muaj 23 chromosomes hauv telophase II, tus naj npawb haploid, n, rau tib neeg. Hauv anaphase II, tus viv ncaus chromatids tam sim no thaum kawg ntawm meiosis kuv tau muab cais ua 23 tus neeg chromosomes.

Tsis tas li ntawd, vim li cas telophase 2 tseem ceeb? Ib lub hnab ntawv nuclear tsim nyob ib ncig ntawm txhua pawg chromosomes. Cytokinesis tshwm sim, tsim plaub tus ntxhais hlwb (gametes, hauv cov tsiaj), txhua tus nrog cov chromosomes haploid. Vim tias hla dhau, qee cov chromosomes tau pom tias muaj cov ntu ntawm cov niam txiv chromosomes qub.

Hais txog qhov no, ua li cas thaum lub sij hawm telophase?

Telophase yog technically theem kawg ntawm mitosis. Nws lub npe muab los ntawm lo lus Latin telos uas txhais tau tias kawg. Thaum theem no, tus muam chromatids ncav cuag tus ncej. Cov vesicles me me hauv lub cell pib rov tsim nyob ib ncig ntawm pawg chromosomes ntawm txhua qhov kawg.

Yuav ua li cas tshwm sim thaum lub sij hawm telophase II ntawm meiosis quizlet?

Nuclear membrane pib tsim nyob ib ncig ntawm haploid pawg ntawm chromosomes.
