Rau kev tshuaj ntsuam genetic tshuaj tiv thaiv kab mob lossis kab mob ntsig txog cov noob caj noob ces, haploid cov hlwb, uas muaj ib pawg ntawm chromosomes, muaj txiaj ntsig ntau dua diploid hlwb.

Ib yam li ntawd, nws raug nug, puas yog kab mob haploid lossis diploid?

Tag nrho kab mob genomes yog haploid , uas yog, lawv tsuas muaj ib daim qauv ntawm txhua tus gene, tshwj tsis yog rau retrovirus genomes, uas yog diploid.

Ib yam li ntawd, haploid thiab diploid yog dab tsi? Diploid cov hlwb muaj ob pawg ua tiav (2n) ntawm chromosomes. Haploid cov hlwb muaj ib nrab ntawm cov chromosomes (n) li diploid - i.e. aw haploid cell muaj tsuas yog ib qho ua tiav ntawm chromosomes. Cell Division thiab Kev Loj Hlob. Diploid cell reproduce los ntawm mitosis ua cov ntxhais cell uas muaj tseeb replicas.

Khaws qhov no hauv kev xav, yog prophase 1 haploid lossis diploid?

Prophase I: Lub xovtooj pib yog diploid, 2n = 4. Homologous chromosomes khub thiab sib pauv cov khoom tawg hauv cov txheej txheem hla. Metaphase I: Homologue khub kab ntawm lub metaphase phaj. Anaphase I: Homologues cais mus rau opposite xaus ntawm tes.
