Nws yog ib qho tseem ceeb uas koj ua raws li cov kauj ruam tsim nyog
- Ua ntej koj yuav tsum tsim kom koj tus menyuam hla kev, lossis P1.
- Tom ntej no koj xav tau ua ib a16 Square Punnett Square rau koj 2 yam koj xav hla.
- Cov kauj ruam tom ntej yog los txiav txim qhov genotypes ntawm ob niam txiv thiab muab lawv tsab ntawv los sawv cev rau alleles .
Ntawm no, hom ntshav li cas piv txwv ntawm ntau yam alleles?
Ib piv txwv ntawm ntau alleles yog ABO ntshav - hom system nyob rau hauv tib neeg. Hauv qhov no, IA thiab kuvB alleles yog codominant nrog ib leeg thiab yog ob qho tib si tseem ceeb tshaj i allele . Txawm tias muaj peb alleles tam sim no nyob rau hauv ib tug pej xeem, txhua tus neeg tsuas tau txais ob ntawm alleles los ntawm lawv niam lawv txiv.
Ib sab saum toj no, Punnett square siv rau dab tsi? Cov Punnett square yog a square daim duab uas yog siv rau kwv yees cov genotypes ntawm ib qho kev hla los yog kev sim ua me me. Nws muaj npe tom qab Reginald C. Punnett , leej twg tsim txoj hauv kev. Daim duab yog siv los ntawm biologists los txiav txim qhov tshwm sim ntawm ib tug me nyuam muaj ib tug tshwj xeeb genotype.
Hais txog qhov no, pes tsawg alleles nyob hauv Codominance?

Koj siv Punnett Square li cas los txiav txim siab hom ntshav?
Muab tus niam lub peev xwm alleles hla kab saum toj kawg nkaus
- Piv txwv li, yog tias leej niam muaj ntshav hom "AB," tsuas yog ib qho kev sib xyaw ua ke uas tuaj yeem tsim tau. Qhov ntawd txhais tau tias koj yuav sau ob lub alleles hauv thawj kab (ib qho A thiab ib qho B).
- Punnett square tuaj yeem siv los txiav txim siab lwm yam zoo ib yam.

Yuav ua li cas koj daws tau ntau kauj ruam sib npaug nrog variables?
Yuav kom daws tau qhov sib npaug zoo li no, koj yuav tsum xub tau txais qhov sib txawv ntawm tib sab ntawm qhov sib npaug. Ntxiv -2.5y rau ob sab kom qhov sib txawv ntawm ib sab nkaus xwb. Tam sim no cais qhov sib txawv los ntawm rho tawm 10.5 ntawm ob sab. Muab ob sab los ntawm 10 kom 0.5y ua 5y, ces faib los ntawm 5
