Cov kauj ruam
- Kos ua 2x2 square .
- Lub npe alleles koom nrog.
- Xyuas cov niam txiv genotypes.
- Sau cov kab nrog ib tus niam txiv lub genotype.
- Sau cov kab nrog rau lwm tus niam txiv lub genotype.
- Kom txhua lub thawv tau txais cov ntawv los ntawm nws kab thiab kab.
- Txhais cov Punnett square .
- Piav qhov phenotype.
Raws li txoj cai, koj yuav pom qhov feem pua ntawm Punnett square?
Faib tus naj npawb ntawm cov thawv nrog ib qho tseem ceeb allele byfourand muab qhov tshwm sim los ntawm 100 kom tau txais feem pua lub caij nyoog uas tus xeeb ntxwv yuav muaj qhov tseem ceeb. Piv txwv li (2/4) * 100 = 50, yog li muaj 50 feem pua muaj feem yuav muaj menyuam muaj qhov muag daj.
Kuj Paub, koj sau genotype li cas? genotype = cov noob ntawm lub cev; foronespecific trait peb siv ob tsab ntawv los sawv cev rau genotype . Ib tsab ntawv loj sawv cev rau daim ntawv tseem ceeb ntawm agene (allele), thiab tsab ntawv me yog cov ntawv luv rau cov qauv ntawm cov noob (allele).
Raws li txoj cai, Punnett Square siv los txiav txim qhov genotype li cas?
Ob yam a Punnett square tuaj yeem qhia koj yog genotypes thiab phenotypes ntawm cov xeeb ntxwv. A genotype yog lub genetic pleev ntawm lub cev. Qhov no qhia los ntawm peb yam kab mob caj ces tau piav qhia ua ntej (BB, Bb, bb). Lub phenotype yog qhov zoo ntawm cov genesexpress.
Ob hom Punnett Squares yog dab tsi?
Hom Punnett Squares Rau cov ntoo khaub lig monohybrid, cov no yog 2X2 squares nrog plaub lub thawv, txhua tus sawv cev rau ib qho xwm txheej fertilization ntawm niam txiv gametes. Qhov thib ob hom yog siv los kwv yees qhov tshwm sim ntawm kev xyaum ua yug me nyuam nyob qhov twg ob traits raug ua raws thiab Punnett square yog loj, nrog rau kaum lub thawv.

Yuav ua li cas koj ua Punnett square nrog ntau alleles?
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 yuav tsum ua 16 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 cov ntawv los sawv cev rau cov alleles
Yuav ua li cas koj pom thaj tsam ntawm daim duab hauv square units?
Thaj tsam yog ntsuas hauv 'square' units. Lub cheeb tsam ntawm daim duab yog tus naj npawb ntawm cov squares yuav tsum tau npog nws tag nrho, zoo li cov vuas rau hauv pem teb. Thaj tsam ntawm ib square = sab sij hawm sab. Txij li txhua sab ntawm ib lub square yog tib yam, nws tuaj yeem tsuas yog qhov ntev ntawm ib sab squared
Yuav ua li cas koj square ib function?
Lub hauv paus muaj nuj nqi yog ib qho kev ua haujlwm ib-rau-ib uas siv tus lej tsis zoo raws li cov tswv yim thiab xa rov qab lub hauv paus square ntawm tus lej ntawd tso tawm. Piv txwv li tus naj npawb 9 tau mapped rau hauv tus naj npawb 3. Lub square muaj nuj nqi yuav siv ib tug xov tooj (zoo los yog tsis zoo) raws li input thiab xa rov qab lub square ntawm tus lej raws li cov zis
Yuav ua li cas koj muab ntau square cag?

Qhia tawm cov squares zoo meej hauv radicand, yog tias ua tau. Muab lub hauv paus square ntawm lub perfectsquare los ntawm cov coefficient
Koj sau Punnett square li cas?
Kos ib lub xwmfab faib ua plaub ntu. Muab txhua tus niam txiv lub genotype saum toj ntawm txhua lub thawv me rau saum lub xwmfab loj, thiab lwm tus niam txiv 'ntawm sab laug (txog nqes) ib sab ntawm txhua lub thawv me. Tus recessive allele, los yog tsab ntawv me, los tom qab tus tsiaj ntawv loj
