| Genotype Cim | Genotype Vocab | Phenotype |
|---|---|---|
| TT | homozygous DOMINANT los yog ntshiab siab | siab |
| Tt | heterozygous los yog hybrid | siab |
| tt | homozygous RECESSIVE los yog ntshiab luv | luv |
Yog li ntawd, TT siab lossis luv?
1/4 yog t t nroj tsuag, uas yog luv thiab tsim xwb luv nroj tsuag tom qab tiam nyob rau hauv tus kheej pollinated. Ntawm qhov seem 3/4 siab zaub, 1/4 yog T T ,qu yog siab thiab tsim xwb siab nroj tsuag nyob rau tiam tom ntej yog hais tias tus kheej pollinated.
Ib yam li ntawd, dab tsi yog qhov genotype ntawm homozygous siab cog? A homozygous siab cog (TT) hla nrog ib tug heterozygous tsob ntoo siab (Tt) (luv luv yog qhov recessive phenotype). Dab tsi yog cov genotypes thiab phenotypes ntawm cov xeeb ntxwv? Q. Ib tug heterozygous dawb luav hla nrog a homozygous luav dub.
Ib yam li ntawd, nws raug nug, dab tsi yog qhov phenotype ntawm TT?
Thaum peb hais cov yam ntxwv ntawm lub cev qhia los ntawm genotype peb tab tom hais yog phenotype . Cov phenotype rau TT yog siab thaum lub phenotype rau tt yog luv. Cov no phenotypes ua tau sib txawv vim ib puag ncig cuam tshuam. Qhov no yog tshwj xeeb tshaj yog muaj tseeb nyob rau hauv cov nqe lus ntawm genotypes thiab phenotypes rau kev txawj ntse.
Dab tsi yog genotypes ntawm cov tib neeg sau npe 1/2 thiab 3?
Tus kheej 1 muaj cov genotype aa. Tus kheej 2 muaj cov genotype Aa. Tus kheej 3 muaj cov genotype Aa.
