Hauv kev ua tsis tiav, lub heterozygote muaj phenotype nruab nrab ntawm cov homozygous-dominant thiab homozygous-recessive cov tib neeg Ib txwm tsis pom kev yog txiav txim los ntawm autosomal dominant noob. Tus me nyuam muaj ntshav hom O yog tias niam txiv tsis yog hom O.
Dab tsi yog qhov heterozygous phenotype rau kev ua tiav tsis tiav?
Nyob rau hauv kev ua tsis tiav, cov phenotype hauv ib tus neeg heterozygous yog visibly qis dua qhov ntawd hauv ib tus neeg homozygous rau tseem ceeb allele, kom AA thiab Aa genotypes tsim cov phenotypes sib txawv. Li no, heterozygote (Aa) yuav muaj phenotype nruab nrab ntawm cov neeg AA thiab aa.
Yuav ua li cas rau qhov phenotype ntawm heterozygous allele hauv kev ua tsis tiav?
Nrog kev tswj tsis tiav, tus neeg heterozygous qhia txog kev sib xyaw ntawm niam txiv ob tus cwj pwm. Tsis yog allele (los yog noob) tau txais txiaj ntsig tag nrho dominates lwm tus; Hloov chaw, ob qhov sib xyaw ua ke rau qhov sib txawv kiag li hauv cov xeeb ntxwv.
Yuav ua tsis tiav dominance yuav heterozygous?
Nyob rau hauv ob qho tib si codominance thiab tsis tiav dominance, ob qho tib si alleles rau qhov zoo tshaj plaws. Nyob rau hauv codominance tus neeg heterozygous qhia ob qho tib si ib txhij yam tsis muaj kev sib xyaw. … Hauv kev tswj tsis tiav ib tus tus neeg heterozygous sib xyaw ob qhov zoo.
Thaum tus heterozygote qhia txog phenotype uas nyob nruab nrab ntawm cov phenotype tseem ceeb thiab rov ua dua?
hom kev sib raug zoo ntawm alleles, nrog rau heterozygote phenotype nruab nrab ntawm ob homozygote phenotypes, hu ua tsis tiav dominance.
