Pleiotropy tshwm sim thaum ib qho kev hloov pauv lossis cov noob / allele cuam tshuam ntau dua ib tus yam ntxwv phenotypic.
Cov xwm txheej twg yog piv txwv ntawm pleiotropy?
Ib qho piv txwv ntawm pleiotropy yog Marfan syndrome, tib neeg caj ces cuam tshuam cuam tshuam rau cov ntaub so ntswg sib txuas. Tus kab mob no feem ntau cuam tshuam rau lub qhov muag, lub plawv, cov hlab ntsha, thiab pob txha. Marfan Syndrome yog tshwm sim los ntawm kev hloov pauv hauv tib neeg cov noob uas ua rau pleiotropy.
Pleiotropy tshwm sim li cas?
Pleiotropy (los ntawm Greek πλείων pleion, "ntau", thiab τρόπος tropos, "txoj kev") tshwm sim thaum ib lub noob cuam tshuam ob lossis ntau qhov zoo li tsis muaj kev cuam tshuam phenotypic zoo. Xws li cov noob uas nthuav tawm ntau qhov kev qhia phenotypic hu ua pleiotropic noob.
Vim li cas pleiotropy thiaj li tshwm sim?
Pervasive pleiotropy
Peb tau paub ntau xyoo lawm tias pleiotropy tau dav vim hauv cov nroj tsuag thiab tsiaj yug tsiaj, thiab hauv kev sim xaiv kev sim, thaum xaiv tau siv rau ib qho qhov zoo, lub ntsiab lus ntawm lwm yam zoo kuj hloov ntawm tiam mus rau tiam.
Pleiotropy ntau npaum li cas?
Frequency of Pleiotropy
Txhua txoj hauv kev, txawm li cas los xij, qhia tias pleiotropy yog ib qho cuab yeej cuab tam nrog 13.2%–18.6% ntawm tag nrho cov noob qhia pleiotropy raws li tau hais hauv qhov no kawm. Thaum cov phenotypes tiv thaiv kab mob tau muab cais ua ib pawg, 189 noob tseem nyob pleiotropic.
