Ib autosome yog ib qho ntawm cov lej chromosomes, as opposed to the sex chromosomes. Tib neeg muaj 22 khub ntawm autosomes thiab ib khub ntawm kev sib deev chromosomes (X thiab Y). Ntawd yog, Chromosome 1 muaj kwv yees li 2,800 noob, thaum chromosome 22 muaj kwv yees li 750 genes.
Ib tug kuj yuav nug, uas chromosome muaj ntau DNA? Cov X chromosome uas muaj nyob rau hauv tib neeg spans ntau tshaj 153 lab puag khub (cov khoom tsim ntawm DNA).
Kuj paub, koj ua li cas txiav txim siab tus naj npawb ntawm autosomes?
Nws yog karyotype tus lej tsawg qhov tus lej ntawm kev sib deev chromosomes. Piv txwv li, nyob rau hauv tib neeg lub cell muaj 46 chromosomes, uas muaj xws li 23 khub ntawm chromosomes. 46 yog karyotype. 23 khub suav nrog 22 khub ntawm autosome hais thiab khub ntawm kev sib deev chromosomes.
Dab tsi yog qhov opposite ntawm autosomal?
Lo lus autosomal ua feem ntau yog hais txog qhov uas muaj feem rau autosomes , uas tsis yog poj niam txiv neej chromosome (as opposed to allosomes or sex chromosomes).
