Ib allele zaus yog xam los ntawm kev faib tus naj npawb ntawm lub sij hawm allele kev txaus siab yog pom nyob rau hauv ib tug pej xeem los ntawm tag nrho cov naj npawb ntawm cov ntawv luam ntawm tag nrho cov alleles ntawm qhov tshwj xeeb genetic locus nyob rau hauv cov pejxeem.

Yog li ntawd, dab tsi yog qhov piv txwv ntawm allele zaus?

Allele Zaus Cia peb xav txog, rau piv txwv , cov pejxeem ntawm 100 diploid cov tib neeg. Yog li tag nrho tus naj npawb ntawm A alleles nyob rau hauv cov pejxeem yuav 20 + 10, rau tag nrho ntawm 30. Cov allele zaus yuav yog tus lej no muab faib los ntawm tag nrho cov lej ntawm cov ntawv luam (30/200) rau 0.15, uas yog allele zaus.

Tsis tas li ntawd, koj yuav suav li cas allele frequencies? Cov zaus ntawm ib qho allele txhais tau tias yog tag nrho cov ntawv luam ntawm qhov ntawd allele nyob rau hauv cov pejxeem muab faib los ntawm tag nrho cov ntawv luam ntawm tag nrho cov alleles ntawm gene. Peb tuaj yeem suav cov pej xeem allele zaus los ntawm genotype tooj.

Ua raws li qhov no hauv kev xav, txhais li cas los ntawm allele zaus?

Allele zaus yog qhov ntsuas ntawm tus txheeb ze zaus ntawm ib allele nyob rau hauv ib tug genetic locus nyob rau hauv ib tug pej xeem. Feem ntau nws yog qhia raws li ib feem lossis feem pua. Hauv cov noob caj noob ces, allele zaus qhia txog kev sib txawv ntawm cov noob caj noob ces ntawm ib hom pejxeem lossis sib npaug ntawm qhov kev nplua nuj ntawm nws cov noob caj noob ces.

Yuav ua li cas koj xam pom zaus hauv Hardy Weinberg?

Suav cov hom aa thiab koj muaj pom q². Tom qab ntawd, muab lub hauv paus square ntawm q² kom tau q, thiab rho q los ntawm 1 kom tau p. square p mus p² thiab muab 2 * p * q kom tau qhov pom heterozygous Aa genotype zaus.
