Txij li thaum p + q =1, ces q = 1 - p. Cov zaus ntawm A alleles yog p2 + pq, uas sib npaug p2 + p (1 - p) = p2 +p -p2 = np; uas yog, p nyob ib yam ntawm ib tiam mus rau lwm tiam.
- Cov zaus ntawm AA tus neeg yuav p2.
- Cov zaus ntawm cov neeg Aa yuav yog 2pq.
- Cov zaus ntawm aa tus neeg yuav q2.
Tom qab ntawd, ib tug kuj yuav nug, ua li cas koj xam allele frequencies?
Allele zaus hais txog yuav ua li cas ib qho allele yog nyob rau hauv cov pejxeem. Nws yog txiav txim los ntawm kev suav pes tsawg zaus tus allele tshwm nyob rau hauv cov pej xeem ces faib los ntawm tag nrho cov luam ntawm cov noob.
Kev xaiv ntuj cuam tshuam li cas rau allele frequencies? Ntuj xaiv kuj cuam tshuam rau allele zaus . Yog ib allele confers ib phenotype uas ua rau ib tug neeg kom muaj sia nyob zoo dua los yog muaj cov xeeb ntxwv ntau dua, cov zaus ntawm qhov ntawd allele yuav nce.
Tsis tas li ntawd, Hardy Weinberg xam cov zaus ntawm allele li cas?
Hauv kev sib npaug ,ua p2 sawv cev rau zaus ntawm homozygous genotype AA, q2 sawv cev rau zaus ntawm homozygous genotype aa, thiab 2pq sawv cev rau zaus ntawm heterozygous genotype Aa. Tsis tas li ntawd, qhov sum ntawm cov allele zaus rau txhua tus alleles ntawm qhov chaw yuav tsum yog 1, yog li p + q = 1.
Dab tsi cuam tshuam rau allele zaus?
Kom meej meej, allele zaus tuaj yeem hloov pauv raws sijhawm hauv ib leeg, thiab feem ntau sib txawv ntawm cov pejxeem. Cov kev sib tham hauv qab no hais txog qhov tseem ceeb tshaj plaws yam cuam tshuam allele zaus : Genetic Isolation, Migration ( noob flow), Mutation, Natural Selection, Artificial Selection, thiab Chance.

Yuav ua li cas koj xam qhov zaus ntawm zaus thiab feem pua?
Ua li no, faib cov zaus los ntawm tag nrho cov txiaj ntsig thiab muab faib los ntawm 100. Hauv qhov no, qhov zaus ntawm thawj kab yog 1 thiab tag nrho cov txiaj ntsig yog 10. Qhov feem pua yog tom qab ntawd yog 10.0. Cov kab kawg yog qhov feem pua Cumulative
Yuav ua li cas koj xam qhov zaus ntawm ib tug photon emission?
Raws li qhov sib npaug E = n⋅h⋅ν (lub zog = tus naj npawb ntawm photons lub sij hawm Planck lub sij hawm tas li lub zaus), yog tias koj faib lub zog los ntawm Planck qhov tas li, koj yuav tsum tau txais photons ib ob. Eh=n⋅ν → lub sij hawm n⋅ν yuav tsum muaj chav nyob ntawm photons / thib ob
Yuav ua li cas koj xam allele zaus?
Ib qho allele zaus yog xam los ntawm kev faib cov naj npawb ntawm lub sij hawm qhov allele ntawm kev txaus siab tau pom nyob rau hauv cov pej xeem los ntawm tag nrho cov ntawv luam ntawm tag nrho cov alleles ntawm qhov tshwj xeeb genetic locus nyob rau hauv cov pejxeem. Allele frequencies tuaj yeem sawv cev ua tus lej, feem pua, lossis ib feem
Kev xaiv ntuj cuam tshuam li cas rau allele zaus?
Kev xaiv ntuj kuj cuam tshuam rau allele zaus. Yog hais tias tus allele confers ib phenotype uas ua rau ib tug neeg kom muaj sia nyob zoo dua los yog muaj cov xeeb ntxwv ntau dua, qhov zaus ntawm allele yuav nce ntxiv
Yuav ua li cas koj saib tom qab willow dome?
Willow Dome Maintenance Dej zoo tam sim ntawd tom qab cog. Kuv ib txwm nyiam dej txhua yam cog tshiab nrog cov hauv paus stimulating chiv. Willows xav tau dej ntau thaum tsim, yog li muab dej txhua hnub rau thawj lub lim tiam, tom qab ntawd txhua hnub rau ob lub lis piam tom ntej
