Txoj kev tswj hwm tsis tiav yog thaum cov phenotypes ntawm ob niam txiv sib xyaw ua ke los tsim cov phenotype tshiab rau lawv cov xeeb ntxwv. Ib qho piv txwv yog paj dawb thiab paj liab ua paj liab. Codominance yog thaum ob niam txiv phenotypes qhia ua ke hauv cov xeeb ntxwv.
Dab tsi yog codominant?
Ib yam tshwm sim los ntawm ib qho allele uas nws tus kheej thiab sib npaug qhia nrog rau lwm tus. Ib qho piv txwv ntawm codominant trait yog hom ntshav, piv txwv li ib tug neeg ntawm cov ntshav hom AB muaj ib tug allele rau cov ntshav hom A thiab lwm yam rau cov ntshav B.
piv txwv ntawm qhov ua tsis tiav yog qhov tseem ceeb?
Cov me nyuam yug los nrog cov plaub hau ib nrab curly los yog wavy yog ib qho piv txwv ntawm cov tib neeg uas muaj kev tswj hwm tsis tiav vim tias kev hla ntawm niam txiv alleles ob qho tib si ncaj thiab curly plaub hau los tsim cov xeeb ntxwv. Yog li, kev tswj hwm tsis tiav tshwm sim los tsim ib qho kev sib tw nruab nrab ntawm ob tus niam txiv zoo.
Puas muaj qhov tseem ceeb hauv Codominance?
Codominance yog ib daim ntawv qub txeeg qub teg nyob rau hauv cov alleles ntawm ib khub noob hauv ib heterozygote tau qhia tag nrho. Yog li ntawd, cov phenotype ntawm cov xeeb ntxwv yog kev sib txuas ntawm cov phenotype ntawm cov niam txiv. Yog li, tus yam ntxwv tsis yog qhov tseem ceeb lossis tsis lees paub.
Dab tsi yog qhov tseem ceeb?
Abstract. Tsis tiav dominance tau los ntawm kev hla hauvuas txhua tus niam txiv txoj kev koom tes yog caj ces tshwj xeeb thiab ua rau cov menyuam yaus uas nws cov phenotype yog nruab nrab. Tsis tiav dominance kuj tseem hu ua semi-dominance thiab ib nrab dominance.
