Hauv qhov no, qhov piv txwv ntawm heterozygous yog dab tsi?

Heterozygous txhais tau hais tias lub cev muaj ob qhov sib txawv ntawm cov noob. Rau piv txwv , pea nroj tsuag canhav liab paj thiab yog homozygous dominant (liab-liab), los yog heterozygous (liab-dawb).

Ib tug kuj yuav nug, homozygous mob yog dab tsi? Homozygous yog caj ces mob qhov twg ib tus neeg txais tau tib lub alleles rau ib qho gene los ntawm ob leeg niam txiv.

Piv txwv ntawm Homozygous Recessive Gene Cov noob albinism nyob ntawm qee qhov chaw, lossis tso rau ntawm DNA strand. Muaj ob hom ntawm cov noob, hu ua alleles.

Ua li cas koj thiaj paub tias nws homozygous lossis heterozygous?

Genotypes, tsis zoo li phenotypes, tuaj yeem ua tau homozygous los yog heterozygous . Yog lub cev yog heterozygous rau ib lub noob, lossis muaj ib qho ntawm txhua tus allele, ces qhov tseem ceeb tshaj plaws yog qhia. Ib qho allele recessive tsuas yog qhia yog lub cev yog homozygous rau qhov zoo li ntawd, los yog muaj ob lub recessive alleles.
