Tag nrho los yog yuav luag tag nrho cov tsiaj txhu diploid kab mob. Tib neeg diploid cov hlwb muaj 46 chromosomes (tus lej somatic, 2n) thiab human haploid gametes (qe thiab phev) muaj 23 chromosomes (n). Retroviruses uas muaj ob daim ntawv theej ntawm lawv cov RNA genome hauv txhua tus kab mob kis kuj tau hais tias yog diploid.
Xav txog qhov no, cov hlwb twg hauv tib neeg yog haploid?
Haploid yog qhov zoo ntawm ib lub xovtooj ntawm tes lossis cov kabmob uas muaj ib txheej ntawm chromosomes . Cov kab mob uas yug me nyuam asexually yog haploid. Cov kab mob sib deev yog diploid (muaj ob pawg ntawm chromosomes , ib tug ntawm txhua tus niam txiv). Hauv tib neeg, tsuas yog lawv lub qe thiab cov phev hlwb yog haploid.
Tsis tas li ntawd, qhov txawv ntawm haploid thiab diploid yog dab tsi? 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.
tib neeg puas muaj cov hlwb haploid?
haploid . Hauv tib neeg , gametes yog cov hlwb haploid uas muaj 23 chromosomes, txhua tus ntawm ib tug ntawm ib tug chromosome khub uas muaj nyob rau hauv diplod hlwb . Tus naj npawb ntawm chromosomes hauv ib txheej yog sawv cev ua n, uas tseem hu ua tus haploid tus lej. Hauv tib neeg ,nqe 23.
Hom cell twg yog diploid?
Diploid. Diploid yog ib lub xovtooj ntawm tes lossis cov kabmob uas muaj cov chromosomes, ib qho ntawm txhua tus niam txiv. Hauv tib neeg, cov hlwb uas tsis yog tib neeg lub cev sib deev, yog diploid thiab muaj 23 khub ntawm chromosomes. Tib neeg lub hlwb (qe thiab phev hlwb) muaj ib txheej ntawm chromosomes thiab hu ua haploid.

Puas yog chimpanzees thiab tib neeg nyob hauv tib genus?
Tib neeg thiab chimpanzees yuav tsum tau muab tso rau hauv tib lub genus, Homo, raws li WSU cov kws tshawb fawb hauv tsab xov xwm Tsib Hlis 19 (#2172) luam tawm hauv Kev Ua Haujlwm ntawm National Academy of Sciences. Cov kev hloov pauv hauv qhov kev txiav txim thawj zaug tau ua rau muaj kev sib cav txog kev hloov pauv
Puas yog meiosis 2 haploid lossis diploid?
Meiosis tsim 4 haploid hlwb. Mitosis tsim 2 diploid hlwb. Lub npe qub rau meiosis yog txo / faib. Meiosis kuv txo qis ploidy theem ntawm 2n mus rau n (txo) thaum Meiosis II faib cov seem ntawm chromosomes hauv cov txheej txheem mitosis zoo li (kev faib)
Puas yog tib neeg muaj feem cuam tshuam nrog gorillas lossis orangutans?
Rau feem ntau DNA sequences, tib neeg thiab chimpanzees zoo li muaj feem xyuam nrog, tab sis qee qhov taw tes rau tib neeg-gorilla lossis chimpanzee-gorilla clade. Tib neeg genome tau ua tiav, nrog rau chimpanzee genome. Tib neeg muaj 23 khub ntawm chromosomes, thaum chimpanzees, gorillas thiab orangutans muaj 24
Puas yog ploidy haploid lossis diploid?
Lo lus ploidy yog hais txog tus lej ntawm cov chromosomes hauv ib lub xovtooj ntawm tes. Cov tsiaj feem ntau yog diploid, muaj ob chromosome. Rau kev tshuaj ntsuam genetic tshuaj tiv thaiv los yog kab mob ntsig txog cov noob caj noob ces, cov hlwb haploid, uas muaj ib pawg chromosomes, muaj txiaj ntsig zoo dua li cov hlwb diploid
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
