Yuav ua kom homozygous rau qhov zoo yog kom muaj ib khub zoo tib yam ntawm cov noob (hu ua alleles) uas txiav txim siab seb nws txhim kho li cas. To be heterozygous for a trait yog kom muaj cov alleles sib txawv rau nws. Ua homozygous rau qhov zoo txhais tau tias nws yuav tig tawm ib yam.

Koj txhais li cas los ntawm H thiab heterozygous?

Homozygous thiab heterozygous yog cov ntsiab lus uas siv los piav txog cov khub allele. Cov tib neeg nqa ob qho tib si alleles (RR los yog rr) hu ua homozygous. Thaum cov kab mob ib leeg muaj cov alleles sib txawv (Rr) hu ua heterozygous.

Hnub no thiab homozygous txawv li cas?

Heterozygous yog hais txog kev muaj ntau hom noob caj noob ces los ntawm txhua tus niam txiv. Ib tug heterozygous genotype sawv cev rau qhov sib txawv ntawm homozygous genotype, qhov twg ib tus neeg tau txais txiaj ntsig zoo ib yam ntawm cov noob caj noob ces los ntawm txhua tus niam txiv.

homozygous thiab heterozygous muaj qhov sib xws?

Ib yam kab mob uas yog homozygous muaj ob daim ntawv ntawm tib qho allele. Ib qho allele yog ib qho version, zoo li "flavor", ntawm cov noob. … Homozygous txhais tau hais tias muaj ob qho tib si allele. Heterozygous txhais tau tias muaj ob qho sib txawv alleles.

Puas yog tib neeg homozygous lossis heterozygous?

Vim tib neeg muaj ob daim ntawv theej ntawm txhua tus chromosome, lawv kuj muaj ob daim ntawv ntawm txhua tus noob thiab qhov chaw ntawm cov chromosomes. Txhua yam ntawm no trait-encodingnoob (los yog loci) hu ua allele. … Yog hais tias cov alleles txawv, tus neeg yog heterozygous rau qhov zoo.
