Qee qhov piv txwv ntawm polygenic yam ntxwv hauv tib neeg yog qhov siab, xim plaub hau, thiab qhov muag xim. Nyob rau hauv cov tsiaj, tus cwj pwm cov yam ntxwv yog tswj los ntawm ntau cov noob. Polygenic cov cim qhia nyob rau hauv tas li variation. Cov neeg uas muaj tib genotype yuav muaj qhov sib txawv phenotype.

Xav txog qhov no, qhov zoo ntawm polygenic txhais li cas?

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 tas mus li, xws li qhov siab lossis xim tawv nqaij, yog polygenic.

Kuj Paub, koj yuav paub li cas yog tias tus cwj pwm yog polygenic? Yog koj yog tus tseem ceeb rau tag nrho cov alleles rau qhov siab, ces koj yuav siab heev. Kuj tseem muaj ntau yam xim ntawm daim tawv nqaij thoob plaws tib neeg. Cov tawv nqaij xim kuj yog ib polygenic zoo , zoo li cov plaub hau thiab qhov muag xim. Polygenic qub txeeg qub teg feem ntau ua rau lub tswb zoo li nkhaus thaum koj txheeb xyuas cov pejxeem (Daim duab hauv qab).

Ntawm no, qhov zoo li cas yog 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 hnyav. Polygenes muaj nyob rau hauv lwm yam kab mob, thiab.

Qhov piv txwv ntawm polygenic trait yog dab tsi?

Cov no noob , hu ua polygenes, tsim tshwj xeeb yam ntxwv thaum lawv qhia ua ke. Piv txwv ntawm polygenic keeb kwm hauv tib neeg suav nrog yam ntxwv xws li tawv nqaij, xim qhov muag, xim plaub hau, lub cev zoo, qhov siab, thiab qhov hnyav.
