Cov qe menyuam hauv cov tsiaj, hu ua gametes, yog piv txwv ntawm haploid hlwb. Ob leeg txiv neej thiab poj niam cov qe menyuam, paub raws li cov phev thiab qe qe, yog haploid nyob rau hauv hais tias lawv txhua tus muaj ib daim qauv ntawm txhua hom chromosome uas, thaum koom nrog lwm tus haploid cell, tsim ib zaug, ua tiav chromosome teeb.

Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog ib qho piv txwv ntawm cov hlwb haploid?

Gametes yog ib qho piv txwv ntawm cov hlwb haploid ua los ntawm meiosis. Piv txwv ntawm gametes yog txiv neej thiab poj niam yug me nyuam hlwb , phev thiab qe cell raws. Cov kab mob uas muaj a haploid Lub neej voj voog muaj xws li feem ntau cov fungi (nrog rau theem dikaryotic), algae (tsis muaj dikaryotic theem) thiab txiv neej ntsaum thiab muv.

Qhov thib ob, peb qhov piv txwv ntawm diploid thiab 3 piv txwv ntawm cov hlwb haploid yog dab tsi? Hauv cov kab mob siab dua, xws li tib neeg, hlwb haploid tsuas yog siv rau kev sib deev hlwb . Hauv cov kab mob siab dua, xws li tib neeg, tag nrho lwm yam hlwb ib sab kev sib deev hlwb yog diploid . Piv txwv ntawm cov hlwb haploid yog gametes (txiv neej lossis poj niam kab mob hlwb ). Piv txwv ntawm cov hlwb diploid suav nrog ntshav hlwb , tawv hlwb thiab nqaij hlwb.

Tsis tas li ntawd, ib qho piv txwv ntawm diploid yog dab tsi?

Diploid cov hlwb muaj ob pawg ua tiav (2n) ntawm chromosomes. Ib lub cell haploid yuav sib koom ua ke nrog lwm lub cell haploid thaum fertilization. Piv txwv . Cov tawv nqaij, ntshav, cov leeg nqaij (tseem hu ua somatic hlwb) Cov hlwb siv hauv kev sib deev, phev thiab ov (tseem hu ua Gametes).

Dab tsi yog haploid cell hauv tib neeg?

Haploid piav a cell uas muaj ib pawg ntawm chromosomes. Lub sij hawm haploid tuaj yeem xa mus rau tus lej ntawm chromosomes hauv qe lossis phev hlwb , uas tseem hu ua gametes. Hauv tib neeg , gametes hlwb haploid uas muaj 23 chromosomes, txhua tus ntawm ib tug ntawm ib tug chromosome khub uas muaj nyob rau hauv diplod hlwb.
