Ib yam li ntawd, qhov zoo li cas yog ib qho piv txwv ntawm qhov muaj nuj nqis hauv tib neeg?

A quantitative zoo yog ib qho kev ntsuas phenotype uas nyob ntawm qhov kev ua ntawm ntau cov noob thiab ib puag ncig. Cov no yam ntxwv tuaj yeem sib txawv ntawm cov tib neeg, dhau ntawm ntau yam, los tsim kev faib tawm txuas ntxiv ntawm phenotypes. Piv txwv suav nrog qhov siab, qhov hnyav thiab ntshav siab.

Cov xim ntawm daim tawv nqaij puas yog qhov zoo? Hauv biology, a qhov zoo yog ib tug yam ntxwv txiav txim los ntawm koj caj ces pleev. Cov plaub hau xim , qhov muag xim , qhov loj me, hom ntshav thiab kab plaub hau yog tag nrho cov piv txwv ntawm kev lom neeg yam ntxwv hauv cov neeg. Cov yam ntxwv zoo yog hom yam ntxwv uas poob rau hauv cov chav kawm sib txawv lossis pawg yam tsis muaj kev hloov pauv hauv cov ntawd yam ntxwv.

Yuav ua li cas yog ib co piv txwv ntawm polygenic zoo?

Polygenic traits muaj ntau yam phenotypes (cov yam ntxwv ntawm lub cev) uas tau txiav txim los ntawm kev sib cuam tshuam ntawm ob peb alleles. Piv txwv ntawm polygenic qub txeeg qub teg hauv tib neeg muaj xws li cov yam ntxwv xws li tawv nqaij xim , qhov muag xim, xim plaub hau, lub cev zoo, qhov siab , thiab hnyav.
