Hauv tib neeg, cov no somatic hlwb muaj ob pawg ntawm chromosomes (ua rau lawv diploid hlwb ). Gametes , ntawm qhov tod tes, muaj kev koom tes ncaj qha rau hauv lub voj voog kev loj hlob thiab feem ntau haploid hlwb , txhais tau tias lawv tsuas muaj ib teeb ntawm chromosomes.
Ib yam li ntawd, qhov txawv ntawm somatic hlwb thiab gametes yog dab tsi?
Somatic hlwb yog qhov pib txhua cell nyob rau hauv lub cev dhau ntawm cov gametes . Nyob rau hauv tib neeg, ib tug diploid cell muaj 46 chromosomes. Gametes yog cov hlwb sib deev , yog li lub qe thiab phev. Lawv suav hais tias haploid vim txhua tus gamete muaj ib nrab ntawm cov chromosomes uas ib tug kab mob somatic hlwb yuav muaj.
Tsis tas li ntawd, qhov sib txawv loj ntawm somatic cell thiab lub qe qe yog dab tsi? Qhov txawv ntawm Somatic Cell thiab Qe Cell . Tus yuam sij qhov sib txawv ntawm somatic cell thiab qe qe qe yog tias somatic cell yog diploid cell uas muaj tag nrho ntawm 46 chromosomes thaum qe qe qe yog haploid cell uas muaj 23 chromosomes.
Yog li ntawd, qhov txawv ntawm somatic hlwb thiab gametes quizlet yog dab tsi?
Somatic -Txhua tus hlwb ntawm "Koj Lub Cev" muaj 46 chromos. Gametes -" Sex Cells "muaj 23 chromos; thaum fertilization tshwm sim txhua tus Gametes yuav pab 23 chromos tshwm sim hauv a Zygote uas muaj qhov qub # ntawm chromos 46. Hauv Meiosis: -Cov txheej txheem muaj nyob tsuas yog ua kom Gametes ( cov hlwb sib deev ).
Dab tsi yog qhov txawv ntawm haploid thiab diploid?
Lub ntsiab qhov sib txawv ntawm haploid cell thiab diploid cell yog diploid cov hlwb muaj ob qhov ua tiav ntawm chromosomes, thaum haploid cov hlwb tsuas muaj ib qho ua tiav ntawm chromosomes. A haploid tus lej yog tus lej ntawm chromosomes hauv lub nucleus ntawm ib chromosomal teeb.
