Ua tiav kev tswj hwm , tsuas yog ib qho allele hauv lub genotype yog pom nyob rau hauv phenotype. Nyob rau hauv codominance, ob leeg alleles nyob rau hauv lub genotype pom nyob rau hauv phenotype. Hauv tsis tiav dominance , sib tov ntawm alleles nyob rau hauv lub genotype yog pom nyob rau hauv phenotype.
Ib yam li ntawd, tib neeg nug, qhov piv txwv ntawm kev ua tsis tiav yog dab tsi?
Thaum ib tug niam txiv uas muaj plaub hau ncaj thiab ib tug nrog cov plaub hau curly muaj ib tug me nyuam nrog wavy plaub hau, uas yog ib tug piv txwv ntawm tsis tiav dominance . Qhov muag xim feem ntau raug suav hais tias yog ib qho piv txwv ntawm tsis tiav dominance.
Tom qab, lo lus nug yog, Codominance thiab tsis tiav dominance yog dab tsi? Hauv tsis tiav dominance tus neeg heterozygous sib xyaw ob qhov zoo. Nrog codominance koj yuav pom ob qho alleles qhia lawv cov teebmeem tab sis tsis sib xyaw nrog tsis tiav dominance koj pom ob qho teebmeem alleles tab sis lawv tau muab sib xyaw.
Kuj paub, lub ntsiab lus ntawm kev ua tsis tiav yog dab tsi?
Tsis tiav dominance yog ib daim ntawv ntawm cov qub txeeg qub teg nyob rau hauv uas ib tug allele rau ib tug tshwj xeeb zoo yog tsis kiag li qhia tag nrho nws cov khub allele. Qhov no tshwm sim nyob rau hauv ib tug thib peb phenotype nyob rau hauv uas qhia lub cev zoo yog ib tug ua ke ntawm cov phenotypes ntawm ob alleles.
Dab tsi yog qhov phenotypic piv ntawm kev ua tsis tiav dominance?

Yuav ua li cas koj paub yog tias nws yog Codominance los yog tsis tiav dominance?
Nyob rau hauv tsis tiav dominance ib tug heterozygous ib tug blends ob yam. Nrog codominance koj yuav pom ob qho tag nrho alleles qhia lawv cov teebmeem tab sis tsis sib xyaw whereas nrog tsis tiav dominance koj pom ob qho tag nrho alleles tab sis lawv tau muab sib xyaw
Yuav ua li cas yog ib tug snapdragon piv txwv ntawm tsis tiav dominance?
Cov paj liab no yog qhov tshwm sim ntawm kev ua tsis tiav. Txawm li cas los xij, kev sib xyaw cov paj liab ua rau ¼ liab, ¼ dawb thiab frac12; liab. Pink snapdragons yog qhov tshwm sim ntawm kev ua tsis tiav. Hla-pollination ntawm liab snapdragons thiab dawb snapdragons ua rau liab dawb thaum tsis yog dawb los yog liab alleles yog dominant
Dab tsi yog qhov tsis tiav dominance hauv noob caj noob ces?
Incomplete dominance yog ib daim ntawv ntawm cov qub txeeg qub teg hauv nruab nrab uas ib qho allele rau ib qho tshwj xeeb tsis qhia tag nrho nws cov khub allele. Qhov no tshwm sim nyob rau hauv ib tug thib peb phenotype nyob rau hauv uas qhia lub cev zoo yog ib tug ua ke ntawm cov phenotypes ntawm ob alleles
Dab tsi yog ua tiav dominance tsis tiav dominance thiab Codominance?
Nyob rau hauv tag nrho dominance, tsuas yog ib tug allele nyob rau hauv lub genotype yog pom nyob rau hauv lub phenotype. Nyob rau hauv codominance, ob alleles nyob rau hauv lub genotype yog pom nyob rau hauv lub phenotype. Nyob rau hauv tsis tiav dominance, ib tug sib tov ntawm alleles nyob rau hauv lub genotype yog pom nyob rau hauv lub phenotype
Dab tsi yog qhov tsis tiav dominance?
Incomplete dominance yog ib daim ntawv ntawm cov qub txeeg qub teg hauv nruab nrab uas ib qho allele rau ib qho tshwj xeeb tsis qhia tag nrho nws cov khub allele. Qhov no tshwm sim nyob rau hauv ib tug thib peb phenotype nyob rau hauv uas qhia lub cev zoo yog ib tug ua ke ntawm cov phenotypes ntawm ob alleles
