Dab tsi yog txhais los ntawm cov noob tseem ceeb thiab cov noob caj noob ces?
(Nyob rau hauv cov ntsiab lus ntawm caj ces, ib qho tseem ceeb tshaj plaws yog ib qho uas yog phenotypically qhia hauv heterozygotes). Ib qho tseem ceeb tshaj plaws yog tawm tsam qhov tsis zoo uas tshwm sim tsuas yog thaum muaj ob daim ntawv theej ntawm cov noob. (Nyob rau hauv cov ntsiab lus genetic, ib tug recessive zoo yog ib tug uas yog phenotypically qhia tsuas yog nyob rau hauv homozygotes)
Hox noob yog dab tsi tshwm sim yog tias Hox noob hloov?
Ib yam li ntawd, kev hloov pauv hauv Hox cov noob tuaj yeem ua rau lub cev thiab cov ceg tawv hauv qhov chaw tsis raug raws lub cev. Zoo li tus thawj coj ua si, Hox noob tsis ua hauv kev ua si lossis koom nrog hauv kev tsim tsa ceg ntawm lawv tus kheej. Cov khoom lag luam protein ntawm txhua Hox gene yog ib qho kev hloov pauv
Puas yog Blonde yog ib qho tseem ceeb lossis cov noob caj noob ces?

Dab tsi yog Codominance hauv cov noob caj noob ces tsis yog Mendelian?
Thaum cov alleles rau ib qho kev coj cwj pwm yog codominant, lawv ob leeg qhia sib npaug es tsis yog ib qho tseem ceeb allele noj tag nrho cov kev tswj ntawm ib qho allele recessive. Qhov no txhais tau hais tias thaum lub cev muaj ob qhov sib txawv alleles (piv txwv li, yog heterozygote), nws yuav qhia ob qho tib si tib lub sijhawm
