Thaum koj nyob nraum heterozygous rau cov noob tshwj xeeb, nws txhais tau tias koj muaj ob qhov sib txawv ntawm cov noob ntawd. Daim ntawv daim ntawv tseem ceeb tuaj yeem npog tag nrho cov khoom tsis zoo, lossis lawv tuaj yeem sib xyaw ua ke. Qee zaum, ob qho tib si versions tshwm sim tib lub sijhawm. Ob lub noob sib txawv tuaj yeem cuam tshuam ntau txoj hauv kev.
Yuav ua li cas ua qub txeeg qub teg uas tshwm sim hauv lub xeev heterozygous tau nthuav tawm raws li kev sib xyaw ntawm ob niam txiv?
Codominance Codominance yog yam ntxwv los ntawm qhov sib npaug, sib txawv, thiab ib txhij qhia ntawm ob niam txiv sib txawv alleles. Cov qauv no txawv ntawm qhov nruab nrab, sib xyaw ua ke pom hauv kev ua tiav tsis tiav. Ib qho piv txwv classic ntawm codominance hauv tib neeg yog ABO hom ntshav.
Puas yog heterozygous yog qhov tseem ceeb lossis rov ua dua?
Heterozygous txhais tau hais tias ib lub cev muaj ob qhov sib txawv ntawm cov noob. Piv txwv li, cov txiv laum huab xeeb tuaj yeem muaj paj liab thiab yog homozygous dominant (liab-liab), lossis heterozygous (liab-dawb). Yog lawv muaj paj dawb ces lawv yog homozygous recessive(dawb-dawb). Cov cab kuj ib txwm heterozygous.
Nws hu li cas thaum tus tseem ceeb thiab recessive allele nyob ua ke?
Codominance =Codominance yog kev sib raug zoo ntawm ob hom ntawm cov noob. Cov tib neeg tau txais ib qho qauv ntawm cov noob, hu ua allele, los ntawm txhua tus niam txiv. Yog tias cov alleles txawv, qhov tseem ceeb ntawm allele feem ntau yuav qhia, thaum cov nyhuv ntawm lwm cov allele, hu ua recessive, yog masked.
Dab tsi yog qhov kev qhia ntawm kev sib xyaw ua ke hauv ib tus neeg heterozygous lossis cov xeeb ntxwv?
Xwb, " codominance" yog lub ntsiab lus tshwj xeeb rau lub kaw lus uas ib qho allele los ntawm txhua tus niam txiv homozygote ua ke hauv cov xeeb ntxwv, thiab cov xeeb ntxwv ib txhij ua ob qho tib si phenotypes. Ib qho piv txwv ntawm codominance tshwm sim nyob rau hauv tib neeg ABO pawg ntshav system.

Kev sib haum xeeb ntawm tib neeg yog ib lub tswv yim uas tau tsim los ntawm Max Weber Rationalization yog hais txog cov txheej txheem los ntawm cov neeg niaj hnub muaj kev txhawj xeeb nrog: Kev Ua Haujlwm: ua tiav cov txiaj ntsig siab tshaj plaws nrog yam tsawg kawg ntawm kev siv zog.
