Meiosis I thiab meiosis II txawv li cas ? Xaiv ob lo lus teb uas yog . Meiosis Kuv yields plaub haploid ntxhais hlwb, whereas meiosis II tawm los ob haploid ntxhais hlwb. Meiosis Kuv faib homologous chromosomes, whereas meiosis II faib cov muam chromatids.
Tom qab ntawd, ib tus tuaj yeem nug, meiosis I thiab meiosis II txawv li cas?
Hauv meiosis Kuv, homologous chromosomes cais, thaum nyob rau hauv meiosis II , tus muam chromatids cais. Meiosis II tsim 4 haploid ntxhais hlwb, whereas meiosis Kuv tsim 2 diploid ntxhais cell. Genetic recombination (hla dhau) tsuas yog tshwm sim hauv meiosis Kuv.
Tom qab ntawd, lo lus nug yog, qhov txawv ntawm meiosis 1 thiab 2 quizlet yog dab tsi? Hauv meiosis I , homologous chromosomes cais tshwm sim hauv a txo ploidy. Txhua tus ntxhais cell muaj xwb 1 teeb ntawm chromosomes. Meiosis II , cais tus muam chromatids sib nrug.
Kuj nug, meiosis 1 thiab 2 zoo li cas?
Ib qho txawv yog qhov ntawd Meiosis 1 pib nrog ib tug diploid cell thiab Meiosis 2 pib nrog 2 cov hlwb haploid, txhua tus muaj ib khub homologous. Meiosis 1 tshwm sim hauv 2 cov ntxhais thiab Meiosis 2 ua 4. Meiosis 2 yog heev zoo sib xws rau Mitosis . Txij li thaum tsis muaj homologous khub (tsuas yog chromatids), recombination tsis tuaj yeem tshwm sim.
Qhov txawv ntawm meiosis II thiab mitosis cov lus teb yog dab tsi?
Qhov loj Qhov sib txawv ntawm meiosis II thiab mitosis yog lub ploidy ntawm lub cell pib. Meiosis II pib nrog ob lub hlwb haploid, uas muaj ib nrab ntawm cov chromosomes li somatic hlwb. Mitosis pib nrog a diploid cell. Nws yuav faib ua ob lub hlwb, ob qho tib si yog diploid.

Dab tsi yog qhov txawv ntawm kev xaiv kev taw qhia thiab kev xaiv cuam tshuam?
Hauv kev xaiv cov kev taw qhia, cov pej xeem cov noob caj noob ces hloov mus rau qhov tshiab phenotype thaum raug kev hloov pauv ib puag ncig. Hauv kev sib txawv lossis kev cuam tshuam kev xaiv, qhov nruab nrab lossis nruab nrab phenotypes feem ntau tsis haum dua li qhov phenotype huab cua thiab tsis zoo li yuav ua rau muaj txiaj ntsig zoo hauv cov pej xeem
Dab tsi yog qhov sib txawv tseem ceeb ntawm kev xaiv cov phooj ywg thiab kev xaiv pab pawg?

Koj txhais li cas los ntawm cov lus teb ib ntus thiab cov lus teb hauv lub xeev khov kho?
Transient Response Tom qab siv cov tswv yim rau kev tswj hwm, tso tawm qee lub sijhawm kom ncav cuag lub xeev khov kho. Yog li ntawd, cov zis yuav nyob rau hauv lub sij hawm ncua mus txog rau thaum nws mus rau asteady xeev. Yog li ntawd, cov lus teb ntawm kev tswj xyuas thaum lub sijhawm hloov pauv lub xeev hu ua transientresponse
