POLYGENIC txhais tau tias a qhov zoo tswj los ntawm ntau tshaj 2 noob, whereas MULTIPLE ALLELES hais txog ntau tshaj 2 hom alleles ib gene. Tus qub muaj ntau tshaj 2 GENE thiab tom qab ntawd muaj ntau tshaj 2 HOM NTAWM LUB TSEV KAWM NTAWV!
Ntxiv mus, vim li cas ntau alleles thiab polygenic traits tsim ntau yam phenotypes rau ib tug zoo?
Qhov no ua tau tshwm sim vim ntau allele cov kev xaiv rau ib tug tshwj xeeb gene qhov ntau tau ua ke thiab yog li ua tau phenotypes lub cev uas muaj cov noob caj noob ces tuaj yeem tau txais txiaj ntsig.
Kuj Paub, yog ntshav hom polygenic lossis ntau alleles? Cov yam ntxwv tswj los ntawm ib lub noob nrog ntau dua ob alleles hu ua ntau allele yam ntxwv. Ib qho piv txwv yog ABO hom ntshav.
Ntau Allele Cov yam ntxwv.
| Genotype | Phenotype (hom ntshav) |
|---|---|
| ii | O |
| KuvAKuvB | AB |
Hauv qhov no, ntau yam allele yog dab tsi?
ntau alleles Peb lossis ntau dua lwm hom qauv ntawm cov noob ( alleles ) uas tuaj yeem nyob hauv tib qhov chaw. Txawm li cas los xij, tsuas yog ob qho tib si alleles tuaj yeem muaj nyob hauv ib lub cev. Piv txwv li, ABO system ntawm pawg ntshav yog tswj los ntawm peb alleles , tsuas yog ob qho uas muaj nyob hauv ib tus neeg.
Yuav ua li cas ntau alleles muab ntau yam phenotypes rau ib tug zoo?
Genes muaj ntau alleles . Cov no alleles tuaj yeem muab ntau yam phenotypes rau qhov zoo . Piv txwv li, ib lub noob rau qhov muag xim muaj variations ntawm alleles uas suav nrog ib allele rau qhov muag xim av, qhov muag xiav, qhov muag ntsuab, thiab lwm yam. Muaj ntau alleles hauv a qhov zoo tuaj yeem ua ntau random ua ke ntawm phenotypes thaum assortment.

Dab tsi yog kev sib raug zoo ntawm alleles thiab noob?
Ib lub noob yog ib feem ntawm DNA uas txiav txim siab txog qhov zoo. Ib qho allele yog ib hom kab mob tshwj xeeb. Cov noob muaj lub luag haujlwm rau kev nthuav qhia cov yam ntxwv. Alleles yog lub luag haujlwm rau cov kev hloov pauv uas qhov kev coj ua tuaj yeem qhia tau
Dab tsi zoo muaj ntau alleles?
Qhov zoo tshaj plaws tus yam ntxwv piv txwv ntawm ntau alleles nyob rau hauv tib neeg yog cov ABO cov ntshav, sib tham nyob rau hauv lub Non-Mendelian Inheritance tswvyim. Lwm yam tib neeg tus cwj pwm txiav txim siab los ntawm ntau yam alleles yuav yog cov plaub hau xim, plaub hau kev ntxhib los mos, qhov muag xim, ua, lub cev, thiab lwm yam
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
Yam dab tsi ntawm cov dej zoo tshaj plaws piav qhia nws lub peev xwm los yaj ntau yam khoom siv?
Vim tias nws cov polarity thiab muaj peev xwm tsim cov ntawv cog lus hydrogen, dej ua rau cov kuab tshuaj zoo heev, txhais tau tias nws tuaj yeem yaj ntau hom molecules
Dab tsi yog ntau yam xwm txheej uas tau khaws cia zoo ib yam hauv kev sim?
Ib qho kev sib txawv yog txhua yam, qhov zoo, lossis qhov xwm txheej uas tuaj yeem muaj nyob hauv ntau qhov sib txawv lossis hom. Ib qho kev sim feem ntau muaj peb hom kev hloov pauv: ywj siab, nyob ruaj khov, thiab tswj tau. Qhov kev hloov pauv ywj pheej yog qhov hloov pauv los ntawm tus kws tshawb fawb
