Txawm li cas los xij, qee zaum cov heterozygote qhia txog phenotype uas yog qhov nruab nrab ntawm cov phenotypes ntawm ob niam txiv homozygote (ib qho uas yog homozygous dominant, thiab lwm yam uas yog homozygous recessive). Qhov nruab nrab phenotype no yog kev ua qauv qhia ntawm ib nrab lossis tsis tiav dominance.
Qhov twg heterozygous qhia qhov nruab nrab phenotype hu ua?
Yog tus phenotype ntawm heterozygous yog nruab nrab ntawm cov phenotype ntawm homozygous, hom kev qub txeeg qub teg yog hais tias yog Tsis tiav Dominance.
Thaum tus heterozygous phenotype yog nruab nrab Qhov no yog piv txwv ntawm?
hom kev sib raug zoo ntawm alleles, nrog rau heterozygote phenotype nruab nrab ntawm ob homozygote phenotypes, hu ua tsis tiav dominance.
Thaum cov phenotype ntawm heterozygote tshwm nyob rau hauv nruab nrab ntawm homozygote phenotypes Qhov no yog hu ua?
Tsis tiav dominance piav qhia txog cov xwm txheej uas tus heterozygote nthuav tawm ib qho phenotype uas yog nruab nrab ntawm homozygous phenotypes. Codominance piav qhia ib txhij ntawm ob qho tag nrho ntawm alleles hauv heterozygote.
Dab tsi phenotype yuav heterozygous qhia?
Qhov kev tswj hwm lossis kev rov ua tau zoo cuam tshuam nrog ib qho allele yog qhov tshwm sim ntawm kev npog ntsej muag, uas yog dominant phenotype hides ib qho phenotype recessive. Los ntawm no logic, nyob rau hauv heterozygous offspring tsuas yog lubphenotype tseem ceeb yuav tshwm sim.
