Codominance txhais tias tsis yog allele tuaj yeem npog qhov kev qhia ntawm lwm tus allele . Ib qho piv txwv ntawm tib neeg yuav yog ABO cov ntshav, qhov twg alleles A thiab alleles B yog ob qho tib si qhia. Yog li ntawd, yog tias tus neeg tau txais txiaj ntsig allele A los ntawm lawv niam thiab allele B los ntawm lawv txiv, lawv muaj ntshav hom AB.

Tsis tas li ntawd, yuav ua li cas tshwm sim thaum ob qho alleles sib npaug?

. Cov yam ntxwv tshwm sim yog vim ob qho tib si alleles raug qhia sib npaug . Ib qho piv txwv ntawm qhov no yog pawg ntshav AB uas yog qhov tshwm sim ntawm kev sib koom ua ke ntawm A thiab B tseem ceeb alleles.

Ib yam li ntawd, muaj pes tsawg alleles nyob hauv Codominance? ob allel

Tsis tas li ntawd, ob leeg alleles tseem nyob hauv Codominance?

tus thawj tswj hwm . Tsis yog tag nrho alleles yog tseem ceeb thiab recessive zoo li cov uas Mendel kawm nyob rau hauv nws cov txiv laum huab xeeb. Codominance , yog ib qho xwm txheej uas ob allele yog sib npaug zog thiab ob allele pom nyob rau hauv hybrid genotype. Ib qho piv txwv ntawm codominance muaj nyob rau hauv qaib.

Qhov twg ob alleles yog codominant nyob rau hauv qub txeeg qub teg ntawm pawg ntshav?

A thiab B alleles yog codominant . Yog li ntawd, yog tias tus A yog tau qub txeeg qub teg los ntawm ib tug niam txiv thiab ib tug B los ntawm lwm tus, tus phenotype yuav yog AB. Kev kuaj Agglutination yuav qhia tau tias cov tib neeg no muaj cov yam ntxwv ntawm ob qho tib si hom A thiab hom B ntshav.
