Nyob hauv tib neeg, tus lej haploid, n sib npaug: 1.
tus lej haploid yog dab tsi rau tib neeg?
Tus naj npawb ntawm chromosomes hauv ib txheej yog sawv cev ua n, uas tseem hu ua tus lej haploid. Hauv tib neeg, n=23.
Puas yog haploid 1n lossis 2n?
Nyob rau hauv cov kab mob sib deev, tus naj npawb ntawm chromosomes hauv lub cev (somatic) cov hlwb feem ntau yog diploid (2n; ib khub ntawm txhua chromosome), ob zaug haploid (1n) tus naj npawb pom nyob rau hauv cov hlwb sib deev, los yog gametes. Tus naj npawb haploid yog tsim thaum lub sij hawm meiosis.
Tus qauv ntawm haploid yog dab tsi?
Cov hlwb somatic hauv cov nplej nplej muaj rau pawg ntawm 7 chromosomes: peb teev los ntawm lub qe thiab peb pawg ntawm cov phev uas fused los tsim cov nroj tsuag, muab tag nrho ntawm 42 chromosomes. Raws li cov qauv, rau cov nplej 2n=6x=42, kom tus lej haploid n yog 21 thiab tus lej monoploid x yog 7.
tus lej diploid thiab haploid yog dab tsi?
Diploid yog ib lub xovtooj ntawm tes lossis kab mob uas muaj chromosomes ua ke, ib qho los ntawm txhua tus niam txiv. Hauv tib neeg, cov hlwb uas tsis yog tib neeg cov hlwb sib deev, yog diploid thiab muaj 23 khub ntawm chromosomesTib neeg cov hlwb (qe thiab phev hlwb) muaj ib pawg chromosomes thiab hu ua haploid.
