Ib qho piv txwv ntawm tib neeg ntau allele qhov zoo yog ABO ntshav hom, uas muaj peb hom alleles: IA, kuvB, thiab i. Piv txwv ntawm tib neeg polygenic yam ntxwv suav nrog cov xim tawv nqaij thiab qhov siab ntawm cov neeg laus. Ntau yam ntxwv raug cuam tshuam los ntawm ib puag ncig, nrog rau cov noob. Qhov no tej zaum yuav muaj tseeb tshwj xeeb rau polygenic yam ntxwv.
Tsuas yog li ntawd, 3 yam piv txwv ntawm polygenic zoo li cas?
Polygenic yam ntxwv muaj lub tswb-puab faib nyob rau hauv cov pej xeem nrog feem ntau cov tib neeg tau txais ntau yam kev sib txuas ntawm alleles thiab poob rau hauv nruab nrab ntawm qhov nkhaus rau ib qho qhov zoo . Piv txwv ntawm polygenic traits suav nrog cov xim ntawm daim tawv nqaij, qhov muag xim, xim plaub hau, lub cev zoo, qhov siab, thiab qhov hnyav.
Ib yam li ntawd, cov piv txwv ntawm polygenic qub txeeg qub teg yog dab tsi? Piv txwv ntawm polygenic qub txeeg qub teg nyob rau hauv cov xwm muaj nyob rau hauv ntau qhov chaw: nyob rau hauv tib neeg qhov siab, xim tawv nqaij, thiab xim plaub hau; nyob rau hauv cov tsiaj loj, ntev, los yog kab mob kuj; thiab nyob rau hauv cov nroj tsuag nrog grain xim, ntev ntawm pob kws, los yog paj loj. Tag nrho cov yam ntxwv no tau cuam tshuam los ntawm ntau cov noob thiab suav tias yog polygenic.
Ntxiv rau qhov no, dab tsi zoo li polygenic hauv tib neeg?
Polygenic qub txeeg qub teg tshwm sim thaum ib tus yam ntxwv raug tswj los ntawm ob lossis ntau dua noob . Feem ntau cov noob muaj ntau ntau tab sis me me siv. Piv txwv ntawm human polygenic inheritance yog qhov siab , tawv nqaij xim , qhov muag xim thiab qhov hnyav. Polygenes muaj nyob rau hauv lwm yam kab mob, thiab.
Cov plaub hau xim puas yog ib qho kev zoo nkauj?
Tib neeg daim tawv nqaij, plaub hau , thiab eye xim kuj yog polygenic yam ntxwv vim lawv raug cuam tshuam los ntawm ntau tshaj ib qho allele ntawm qhov chaw sib txawv.

Puas yog kev coj cwj pwm yog qhov zoo ntawm polygenic?
Qee qhov piv txwv ntawm polygenic zoo nyob rau hauv tib neeg yog qhov siab, xim plaub hau, thiab qhov muag xim. Hauv cov tsiaj, tus cwj pwm coj cwj pwm yog tswj los ntawm ntau cov noob. Cov cim polygenic tau nthuav tawm hauv kev hloov pauv tas mus li. Cov neeg uas muaj tib genotype yuav muaj qhov sib txawv phenotype
