Qhov zoo tshaj plaws characterized piv txwv ntawm ntau alleles nyob rau hauv tib neeg yog pawg ABO cov ntshav, sib tham hauv Non-Mendelian Inheritance tswvyim. Lwm tus neeg yam ntxwv txiav txim los ntawm ntau alleles yuav yog cov plaub hau xim, plaub hau kev ntxhib los mos, qhov muag xim, ua, lub cev qauv, thiab lwm yam.
Hais txog qhov no, dab tsi yog qhov zoo nrog ntau tus alleles?
A ntau yam allele zoo yog thaum muaj ntau tshaj ob alleles uas muaj nyob rau hauv cov pejxeem. Alleles tuaj yeem yog qhov tseem ceeb lossis rov ua dua, tuaj yeem npog txhua qhov
Ib yam li ntawd, dab tsi yog qhov ntau yam ntawm noob caj noob ces? Ib tug "polygene" los yog " ntau gene qub txeeg qub teg" yog ib tug tswv cuab ntawm ib pab pawg neeg uas tsis yog epistatic noob uas cuam tshuam ntxiv rau cuam tshuam rau phenotypic qhov zoo . Hauv qhov xwm txheej zoo li no a noob raug txheeb xyuas, nws raug xa mus rau qhov ntau qhov zoo locus (QTL). Cov no noob feem ntau yog pleiotropic thiab.
Ua kom pom qhov no, piv txwv ntawm ntau yam alleles yog dab tsi?
Piv txwv ntawm Ntau Alleles Ob tug neeg piv txwv ntawm ntau yam - allele Cov noob yog cov noob ntawm ABO cov ntshav pawg system, thiab human-leukocyte-associated antigen (HLA) genes. ABO system nyob rau hauv tib neeg yog tswj los ntawm peb alleles , feem ntau hu ua IA, kuvB, thiab kuvO (tus "Kuv" sawv cev rau isohaemagglutinin).
Muaj pes tsawg alleles nyob rau hauv ib tug zoo?

Dab tsi yog ntau yam alleles thiab polygenic zoo?
POLYGENIC txhais tau hais tias tus cwj pwm tswj hwm los ntawm ntau dua 2 cov noob, thaum MULTIPLE ALLELES hais txog ntau dua 2 hom alleles ntawm cov noob. Tus qub muaj ntau dua 2 GENES thiab tom qab ntawd muaj ntau dua 2 HOM NTAWM LUB TSEV KAWM NTAWV
Dab tsi yog txhais los ntawm ntau alleles?
Txhais thiab Piv Txwv Ntau yam alleles yog hom tsis yog-Mendelian qub txeeg qub teg uas muaj ntau tshaj li ob qho alleles uas feem ntau yog code rau qee yam cwj pwm hauv ib hom. Lwm cov alleles tuaj yeem koom ua ke ua ke thiab qhia lawv qhov zoo sib xws hauv cov phenotype ntawm tus neeg
Koj puas tuaj yeem muaj ntau dua 2 alleles rau cov noob?
Txawm hais tias ib tus neeg feem ntau tsuas muaj ob qho alleles rau cov noob, ntau tshaj li ob lub alleles tuaj yeem muaj nyob hauv cov pej xeem cov gene pool. Raws li txoj cai, txhua qhov kev hloov pauv hauv paus yuav ua rau muaj tus allele tshiab. Qhov tseeb, nyob rau hauv tib neeg cov pej xeem, nws yuav muaj kev nyab xeeb hais tias feem ntau tib neeg cov noob muaj ntau tshaj ob alleles
Dab tsi yog DNA zoo li cuam tshuam nws cov qauv tshuaj rau nws zoo li cas thaum muaj ntau ntawm nws yog clumped ua ke?
Hais txog nws cov qauv tshuaj rau nws zoo li cas thaum ntau nws yog clumped ua ke. DNA zoo li kab laug sab webs. DNA tau soluble hauv DNA extraction tsis yog li peb tsis pom nws. Thaum nws tau stirred rau hauv ethanol, nws clumped ua ke thiab tsim thicker thiab thicker strands loj txaus kom pom
Yuav ua li cas muaj pes tsawg tus noob sib xyaw ua tau hauv gamete ntau lawm rau Dihybrid cross Vim li cas thiaj muaj ntau?
Muaj peev xwm gametes rau txhua tus niam txiv AaBb Txij li thaum txhua tus niam txiv muaj plaub qhov sib txawv ntawm cov alleles hauv gametes, muaj kaum rau kev sib txuas ua ke rau tus ntoo khaub lig no
