Homozygous txhais. Yog tias cov alleles zoo ib yam, koj yog homozygous rau qhov tshwj xeeb gene. Piv txwv li, nws tuaj yeem txhais tau tias koj muaj ob lub alleles rau cov noob uas ua rau lub qhov muag xim av. Qee cov alleles tseem ceeb, thaum lwm tus yog recessive. Qhov tseem ceeb ntawm allele yog qhia ntau zog, yog li nws npog lub recessive allele.

Kuj nug, piv txwv li heterozygous yog dab tsi?

Heterozygous txhais tau hais tias ib tug kab mob muaj ob tug sib txawv alleles ntawm ib tug noob. Rau piv txwv , pea nroj tsuag tuaj yeem muaj paj liab thiab yog homozygous dominant (liab-liab), los yog heterozygous (liab-dawb). Yog hais tias lawv muaj paj dawb, ces lawv yog homozygous recessive (dawb-dawb). Cov neeg nqa khoom ib txwm muaj heterozygous.

Tsis tas li ntawd, homozygous mob yog dab tsi? Homozygous piav txog cov caj ces mob los yog lub xeev caj ces qhov twg ib tug neeg tau txais tib lub DNA ib ntus rau ib lub noob caj noob ces los ntawm ob leeg niam thiab lawv txiv yug. Nws yog feem ntau siv nyob rau hauv cov ntsiab lus ntawm kab mob.

Yog lawm, yog cov plaub hau xim av homozygous?

Yog neb ob leeg muaj plaub hau xim av , ces koj yuav tau txais qub txeeg qub teg plaub hau xim av alleles los ntawm lawv ob leeg. Vim koj yuav muaj ob yam tib yam plaub hau xim av alleles, koj yuav yog homozygous rau qhov zoo. Yog hais tias ib tug niam txiv yog blonde thaum lwm tus muaj plaub hau xim av , koj tuaj yeem tau txais ib qho xim daj thiab ib qho plaub hau xim av allele.

Homozygous txhais li cas hauv biology?

Homozygous hais txog muaj cov alleles zoo tib yam rau ib qho kev zoo. Ib qho allele sawv cev rau ib hom ntawm cov noob. Alleles ua tau muaj nyob rau hauv ntau hom thiab diploid kab mob feem ntau muaj ob alleles rau ib tug muab zoo. Thaum fertilization, alleles yog randomly koom ua ke raws li homologous chromosomes khub.
