(Hauv caj ces lus, a tseem ceeb Qhov zoo yog ib qho uas yog phenotypically qhia hauv heterozygotes). A tseem ceeb qhov zoo yog tawm tsam a rov ua dua tus cwj pwm uas tau nthuav tawm tsuas yog thaum ob daim ntawv theej noob muaj nyob. (Hauv caj ces lus, a rov ua dua Qhov zoo yog ib qho uas yog phenotypically qhia tsuas yog hauv homozygotes).

Ib yam li ntawd ib tug yuav nug, dab tsi yog txhais los ntawm cov noob tseem ceeb thiab cov noob caj noob ces?

Dominant thiab recessive yam ntxwv muaj nyob thaum tus cwj pwm muaj ob hom sib txawv ntawm qhov noob qib. Qhov zoo uas thawj zaug tshwm sim los yog pom tau pom hauv lub cev yog hu ua tseem ceeb qhov zoo. Qhov zoo uas muaj nyob rau hauv noob qib tab sis yog npog thiab tsis qhia nws tus kheej hauv lub cev yog hu ua rov ua dua qhov zoo.

dab tsi yog lub ntsiab lus ntawm dominant gene? 1. cov gene - noob uas ua rau tib phenotype nyob rau hauv lub cev txawm los yog tsis nws allele zoo tib yam; "cov cov gene rau qhov muag xim av"

Kuj paub yog, nws txhais li cas kom muaj cov noob caj noob ces?

A recessive noob yog ib noob uas tuaj yeem npog los ntawm tus thawj noob . Nyob rau hauv thiaj li yuav muaj ib tug zoo li ntawd yog qhia los ntawm a recessive noob , xws li lub qhov muag xiav, koj yuav tsum tau tus noob rau ob lub qhov muag xiav ntawm koj niam koj txiv.

Dab tsi ua rau lub gene los ua tus tseem ceeb?

Thaum peb tham txog noob ua tseem ceeb los yog recessive, peb feem ntau tham txog cov yam ntxwv tswj los ntawm tus nqi ntawm cov protein ntau tsim. Yog noob yog tswj cov txheej txheem uas tag nrho cov alleles yuav tsum tau nyob rau tib nplooj ntawv nyob rau hauv cov nqe lus ntawm protein ntau lawm, lub cov gene yuav yog tus uas tawg.
