Ib yam li qhov muag lossis cov plaub hau xim, peb hom ntshav tau txais los ntawm peb niam txiv. Txhua leej niam leej txiv pub ib qho ntawm ob hom ABO rau lawv tus menyuam. Cov noob A thiab B yog qhov tseem ceeb thiab O noob yog rov ua dua. Piv txwv li, yog tias O gene ua ke nrog A gene, hom ntshav yuav yog A.
Vim li cas ntshav hom O recessive?
Cov noob rau hom O yog 'recessive', vim yog tias koj muaj ib lub noob rau O thiab ib qho rau A, ces koj tseem yuav xaus nrog A antigens ntawm koj lub cell membranes, thiab tib yam mus. rau O thiab B. Yuav kom ua pab pawg O, koj xav tau ob lub hlwb niam txiv los ua O. Tab sis pawg O tseem muaj ntau dua vim tias nws yog daim ntawv poj koob yawm txwv.
hom ntshav twg yog qhov tseem ceeb tshaj?
Qhov xav tau O+ yog qhov siab vim nws yog hom ntshav tshwm sim ntau tshaj plaws (37% ntawm cov pejxeem). Tus neeg mob ntshav qab zib thoob ntiaj teb muaj ntshav hom O tsis zoo. Tus neeg pub ntshav plasma universal muaj hom AB ntshav.
hom ntshav twg yog qhov txo qis tshaj plaws?
O hom yog qhov ntau tshaj plaws txawm tias yog cov noob caj noob ces vim tias nws tau nthuav tawm ntau hauv cov noob caj noob ces, thaum hom A thiab hom B yog qhov tseem ceeb (thiab hom AB yog codominant) tab sis tsis tshua muaj ntau vim tias lawv tsis tshua qhia hauv cov noob caj noob ces.
O ob niam txiv zoo puas muaj tus menyuam zoo?
Ob o niam txiv yuav tau tus me nyuam yuav luag txhua lub sijhawm. Tab sis nws yog technically ua tau rau ob tug O-hom niam txiv kom muaj menyuam nrogA lossis B ntshav, thiab tej zaum txawm tias AB (txawm tias qhov no yeej tsis zoo li). Qhov tseeb, tus menyuam tuaj yeem tau txais yuav luag txhua hom ntshav yog tias koj xav txog qhov cuam tshuam ntawm kev hloov pauv. Qhov no tshwm sim li cas?
