A noob yog ib chav tsev ntawm cov ntaub ntawv keeb kwm yav dhau los. Cov lus teb luv luv yog tias ib allele yog ib daim ntawv variant ntawm a noob . Piav qhia ntau dua, txhua tus noob nyob ntawm ib qho chaw tshwj xeeb (qhov chaw ntawm chromosome) hauv ob daim ntawv, ib daim ntawv luam ntawm noob tau txais los ntawm txhua tus niam txiv. Cov ntawv luam, txawm li cas los xij, tsis tas yuav zoo ib yam.
Tsis tas li lo lus nug yog, qhov txawv ntawm allele thiab noob yog dab tsi?
A noob yog ib feem ntawm DNA uas txiav txim siab ib yam dab tsi. Ib allele yog ib daim ntawv tshwj xeeb ntawm a noob . Cov noob muaj lub luag haujlwm rau kev nthuav qhia ntawm qhov zoo. Alleles yog lub luag hauj lwm rau cov variations nyob rau hauv uas ib tug muab kev zoo yuav qhia tau hais tias.
Tsis tas li ntawd, dab tsi yog allele hauv biology? Ib allele yog ib yam ntawm cov gene. Feem ntau cov noob muaj ob alleles , ib dominant allele thiab ib tug recessive allele . Yog hais tias lub cev yog heterozygous rau qhov zoo, los yog muaj ib qho ntawm txhua tus allele , ces tus cwj pwm tseem ceeb yog qhia. Yog li cov noob yog ib cheeb tsam tshwj xeeb ntawm koj cov DNA uas tswj hwm qhov tshwj xeeb.
Ib yam li ntawd, dab tsi yog cov noob chromosome thiab allele?
Allele . Ib allele yog ib qho kev xaiv ntawm a noob (hauv diploids, ib tug tswv cuab ntawm ib khub) uas nyob ntawm ib txoj hauj lwm ntawm ib qho tshwj xeeb chromosome . Cov kab mob Diploid, piv txwv li, tib neeg, tau ua ke homologous chromosomes hauv lawv cov hlwb somatic, thiab cov no muaj ob daim ntawv luam ntawm txhua tus noob.
Alleles cuam tshuam li cas rau cov noob?
Cov noob muaj nyob rau hauv cov qauv hu ua chromosomes, ntev pieces ntawm DNA raug mob nyob ib ncig ntawm cov protein. Txhua chromosome muaj ntau, ntau noob . Thiab ib qho tshwj xeeb noob , zoo li cov noob rau qhov muag xim, yog nyob rau tib qhov chaw ntawm tib chromosome nyob rau hauv txhua tus neeg. Qhov txawv tau versions ntawm lub noob hu ua alleles.

Dab tsi yog txhais los ntawm cov noob tseem ceeb thiab cov noob caj noob ces?
(Nyob rau hauv cov ntsiab lus ntawm caj ces, ib qho tseem ceeb tshaj plaws yog ib qho uas yog phenotypically qhia hauv heterozygotes). Ib qho tseem ceeb tshaj plaws yog tawm tsam qhov tsis zoo uas tshwm sim tsuas yog thaum muaj ob daim ntawv theej ntawm cov noob. (Nyob rau hauv cov ntsiab lus genetic, ib tug recessive zoo yog ib tug uas yog phenotypically qhia tsuas yog nyob rau hauv homozygotes)
Hox noob yog dab tsi tshwm sim yog tias Hox noob hloov?
Ib yam li ntawd, kev hloov pauv hauv Hox cov noob tuaj yeem ua rau lub cev thiab cov ceg tawv hauv qhov chaw tsis raug raws lub cev. Zoo li tus thawj coj ua si, Hox noob tsis ua hauv kev ua si lossis koom nrog hauv kev tsim tsa ceg ntawm lawv tus kheej. Cov khoom lag luam protein ntawm txhua Hox gene yog ib qho kev hloov pauv
Dab tsi yog qhov txawv ntawm kev xaiv khoom tsim thiab kev tsim noob caj noob ces?
Artificial xaiv xaiv rau cov yam ntxwv uas twb muaj nyob rau hauv ib hom, whereas genetic engineering tsim cov yam ntxwv tshiab. Hauv kev xaiv dag, cov kws tshawb fawb yug tsuas yog cov tib neeg uas xav tau qhov zoo. Los ntawm kev xaiv kev yug me nyuam, cov kws tshawb fawb muaj peev xwm hloov cov cwj pwm hauv cov neeg. Evolution tau tshwm sim
Dab tsi yog lub luag haujlwm ntawm cov noob caj noob ces thiab chromosomes hauv kev xeeb tub?
Heredity plays lub luag haujlwm tseem ceeb hauv kev loj hlob ntawm cov yam ntxwv thiab kis tau los ntawm cov noob. Cov yam ntxwv uas peb tau txais los pab txhim kho peb tus cwj pwm, txiav txim siab los ntawm khub niam txiv, ib qho los ntawm txhua tus niam txiv. Cov noob muaj nyob hauv cov qauv zoo li hu ua chromosomes, uas yog tsim los ntawm DNA
Dab tsi yog Codominance hauv cov noob caj noob ces tsis yog Mendelian?
Thaum cov alleles rau ib qho kev coj cwj pwm yog codominant, lawv ob leeg qhia sib npaug es tsis yog ib qho tseem ceeb allele noj tag nrho cov kev tswj ntawm ib qho allele recessive. Qhov no txhais tau hais tias thaum lub cev muaj ob qhov sib txawv alleles (piv txwv li, yog heterozygote), nws yuav qhia ob qho tib si tib lub sijhawm
