Nws yog ib qhov zoo uas qhia txog cov haujlwm ntawm ntau tshaj ib lub noob thiab tsis cuam tshuam los ntawm ib puag ncig. Piv txwv li: qhov siab, tawv nqaij xim, lub cev hnyav, mob, tus cwj pwm. multifactorial - ob leeg ib tug noob thiab polygenic yam ntxwv tuaj yeem yog qhov no. Nws txhais tau tias lawv raug cuam tshuam los ntawm ib puag ncig.

Yog li ntawd, nws txhais li cas rau qhov zoo ntawm ob qho tib si polygenic thiab multifactorial chegg?

Ntau cov noob caj noob ces tsim cov yam ntxwv ntawm a qhov zoo , thiab ib puag ncig yam cuam tshuam rau kev qhia ntawm cov noob no. Ib qho allele yog lub luag haujlwm rau ib qho tshwj xeeb qhov zoo , tab sis nws cov lus qhia ua tau hloov los ntawm ntau yam ib puag ncig.

Tsis tas li ntawd, nws txhais li cas yog tias tus cwj pwm yog polygenic? A polygenic zoo yog ib qho uas nws phenotype cuam tshuam los ntawm ntau tshaj ib lub noob. Cov yam ntxwv uas tso saib kev faib tawm tsis tu ncua, xws li qhov siab lossis xim tawv nqaij, yog polygenic.

Qhov thib ob, tus cwj pwm puas tuaj yeem yog polygenic thiab multifactorial?

Nws ua tau yuav hais tias polygenic qub txeeg qub teg muaj complex yam ntxwv uas tau txiav txim los ntawm ntau cov noob ntawm cov chaw sib txawv, tsis muaj kev cuam tshuam ntawm ib puag ncig. Ntawm qhov tod tes, multifactorial qub txeeg qub teg piav txog a qhov zoo nws manifestations yog txiav txim los ntawm ob los yog ntau tshaj cov noob, nrog rau ib puag ncig yam.

Multifactorial trait yog dab tsi?

Multifactorial qub txeeg qub teg txhais tau hais tias muaj ntau yam ( multifactorial ) koom nrog ua rau muaj teeb meem kev noj qab haus huv. Cov xwm txheej feem ntau yog ob qho tib si caj ces thiab ib puag ncig. Kev sib xyaw ntawm cov noob los ntawm ob niam txiv ntxiv rau qhov tsis paub txog ib puag ncig ua rau qhov zoo los yog mob. Ib qho piv txwv ntawm a multifactorial zoo yog qhov siab.
