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.
Ua raws li qhov no, qhov twg yog qhov piv txwv ntawm kev ua tsis tiav?
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 ntawd, lo lus nug yog, Incomplete Dominance ua haujlwm li cas? Tsis tiav dominance 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.
Tsis tas li ntawd, dab tsi ua tiav thiab tsis tiav dominance?
Hauv ua tiav dominance , tsuas yog ib qho allele hauv genotype pom hauv phenotype. Nyob rau hauv codominance, ob alleles nyob rau hauv lub genotype yog pom nyob rau hauv lub phenotype. Hauv tsis tiav dominance , sib tov ntawm alleles nyob rau hauv lub genotype yog pom nyob rau hauv lub phenotype.
Ib qho piv txwv ntawm kev tswj hwm tag nrho yog dab tsi?
Cov paj ntawm Mendel's pea cog yog ib qho piv txwv ntawm tag nrho dominance , los yog thaum twg tseem ceeb allele tag npog li recessive allele. Ntxiv rau ua tiav dominance , cov kws tshawb fawb pom tias tsis tiav kev tswj hwm , qhov twg muaj kev sib xyaw, thiab kev sib koom ua ke, qhov twg ob leeg alleles tshwm sim.

Yog vim li cas combustion tiav yog zoo dua li tsis tiav combustion?
Tsis tiav combustion tshwm sim thaum cov khoom cua lossis oxygen tsis zoo. Dej tseem tsim, tab sis carbon monoxide thiab carbon yog tsim los ntawm carbon dioxide. Cov pa roj carbon yog tso tawm raws li cov kua qaub. Cov pa roj carbon monoxide yog cov pa tshuaj lom, uas yog ib qho laj thawj vim li cas kev sib xyaw ua tiav yog nyiam rau kev ua tsis tiav
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
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 genotype ntawm kev ua tsis tiav dominance?
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
