Hauv cov kab mob diploid, heterozygous hais txog ib tus neeg muaj ob qho alleles sib txawv rau ib qho kev tshwj xeeb. Ib qho allele yog cov qauv ntawm cov noob caj noob ces lossis cov DNA tshwj xeeb ntawm cov chromosome. A heterozygous cog yuav muaj cov alleles hauv qab no rau cov noob zoo: (Rr).
Kuj nug, heterozygous txhais li cas?
heterozygous . Yog tias ob lub alleles ntawm ib qho chaw zoo ib yam rau ib leeg, lawv yog homozygous; yog lawv txawv ib leeg xwb heterozygous . Zoo li tag nrho cov lus nrog prefix hetero, heterozygous tau ua nrog tej yam uas txawv - tshwj xeeb yog noob.
Ib yam li ntawd, dab tsi yog heterozygous genotype? heterozygous genotype (HEH-teh-roh-ZY-gus JEE-noh-tipe) tshwm sim thaum ob lub alleles ntawm ib qho chaw tshwj xeeb yog txawv. A heterozygous genotype tej zaum yuav muaj xws li ib txwm allele thiab ib qho kev hloov pauv, lossis ob qhov kev hloov pauv sib txawv. Cov tom kawg yog hu ua compound heterozygote.
Kuj paub yog, homozygous txhais li cas hauv kev tshawb fawb?
Homozygous yog ib lo lus uas hais txog cov noob caj noob ces uas muaj cov alleles zoo tib yam ntawm ob homologous chromosomes. Nws raug xa mus los ntawm ob tus tsiaj ntawv loj (XX) rau qhov tseem ceeb, thiab ob tus tsiaj ntawv me (xx) rau qhov zoo.
Dab tsi yog heterozygous noob mutation?
Heterozygous yog ib lo lus siv nyob rau hauv genetics los piav txog thaum ob variations ntawm a noob (lub npe hu ua alleles) yog khub ntawm tib qhov chaw (locus) ntawm chromosome. Los ntawm qhov sib txawv, homozygous yog thaum muaj ob daim ntawv luam ntawm tib lub allele ntawm tib qhov chaw.
