Kos ib square muab faib ua plaub ntu. Muab txhua tus niam txiv lub genotype saum toj ntawm txhua lub thawv me rau saum qhov loj square , thiab lwm tus niam txiv 'ntawm sab laug (txog nqes) ib sab ntawm txhua lub thawv me me. Tus recessive allele, los yog tsab ntawv me, los tom qab tus tsiaj ntawv loj.
Raws li, Punnett squares ua haujlwm li cas?
Cov Punnett square yog ib daim duab square uas yog siv los kwv yees cov genotypes ntawm ib qho kev sib tw los yog kev ua liaj ua teb. Nws muaj npe tom qab Reginald C. Punnett , leej twg tsim txoj hauv kev. Daim duab kos yog siv los ntawm biologists los txiav txim qhov tshwm sim ntawm ib tug xeeb ntxwv uas muaj ib qho genotype.
Ib sab saum toj no, Kuv yuav ua li cas Punnett Square hauv Lo Lus? Muaj cov kauj ruam hauv qab no uas peb tuaj yeem ua tau kos ib Punnett square yooj yim hauv MS Lo lus : Kauj Ruam 1: Kos a square ntawm 2 * 2, Sau tag nrho cov alleles koom. Kauj Ruam 2: Txheeb xyuas cov genotypes rau cov niam txiv. Kauj Ruam 3: Sau nws cov kab nrog cov genotype ntawm ib tus niam txiv, tom qab ntawd, sau cov kab.
Tom qab ntawd, ib tus tuaj yeem nug, koj ua Punnett squares nrog ob qhov zoo li cas?
Nws yog ib qho tseem ceeb uas koj ua raws li cov kauj ruam tsim nyog
- Ua ntej koj yuav tsum tsim kom muaj koj tus niam txiv ntoo khaub lig, lossis P1.
- Tom ntej no koj yuav tsum ua 16 square Punnett Square rau koj 2 yam koj xav hla.
- Cov kauj ruam tom ntej yog los txiav txim cov genotypes ntawm ob niam txiv thiab muab lawv cov ntawv los sawv cev rau cov alleles.
Punnett Squares yog dab tsi?
Nws zoo kawg nkaus raug , raws li nws mus. Ntawd yog, nws raug piav qhia txog kev sib raug zoo ntawm alleles thiab Mendelian phenotypes. Txawm li cas los xij, zoo li hauv txhua qhov kev tshawb fawb, lub ntiaj teb tiag tiag yog qhov nyuaj dua li kev xav.
