Alleles yog alternate daim ntawv ntawm ib tug gene uas muaj tib qhov chaw ntawm ib khub ntawm homologous chromosomes. Alleles yog dab tsi? Ib qho tseem ceeb allele yuav raug phenotypically qhia txawm tias lwm tus allele tsis zoo ib yam. Recessive traits muaj ntau dua vim hais tias muaj ntau recessive alleles nyob rau hauv ib tug pej xeem.
Ntawm no, dab tsi yog qhov hloov pauv ntawm cov gene?
Ib lwm daim ntawv ntawm ib tug gene lub npe hu ua allele. Alleles sib txawv nyob rau hauv lawv ib ntus uas tej zaum yuav los yog tsis ua rau ib tug variant phenotype ntawm ib tug tshwj xeeb zoo. Alleles sawv cev variations ntawm a noob uas yog lub luag hauj lwm rau ib tug yam ntxwv.
Ib yam li ntawd, puas yog ib qho ntawm ob lossis ntau hom kev hloov pauv ntawm cov noob? Ib qho allele yog ib qho lwm daim ntawv ntawm ib tug gene (hauv diploids, ib tus tswv cuab ntawm ib khub) uas nyob ntawm ib txoj hauj lwm tshwj xeeb ntawm ib qho 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 ib daim ntawv luam ntawm txhua tus noob.
Tsis tas li ntawd, cov ntawv hloov pauv ntawm cov noob hu ua quizlet yog dab tsi?
Ib qho allele yog ib qho ntawm cov lwm cov qauv ntawm ib tug (gene / genome) uas yuav tshwm sim ntawm ib qho tshwj xeeb (locus / trait). Yog hais tias ib khub ntawm alleles yog tib yam, lawv yog hu ua (heterozygous / homozygous).
Dab tsi macromolecule yog tsim los ntawm cov lus qhia muaj nyob rau hauv cov noob caj noob ces?
Nucleic acids

Dab tsi yog qhov txawv ntawm ib puag ncig kev hloov pauv thiab kev hloov pauv qub txeeg qub teg?
Qhov sib txawv ntawm cov yam ntxwv ntawm cov tib neeg ntawm tib hom yog hu ua variation. Qhov no yog inherited variation. Qee qhov kev hloov pauv yog qhov tshwm sim ntawm qhov sib txawv ntawm ib puag ncig, lossis ib tus neeg ua dab tsi. Qhov no yog hu ua environmental variation
Dab tsi tsim cov roj siab thiab nws hloov pauv li cas nrog kev hloov pauv hauv kinetic zog?
Gas siab yog tshwm sim los ntawm kev sib tsoo ntawm cov khoom siv roj nrog rau sab hauv ntawm lub thawv thaum lawv sib tsoo nrog thiab tawm dag zog rau ntawm phab ntsa ntim. Tom qab ntawd cov roj yog cua sov. Raws li qhov kub ntawm cov roj nce, cov khoom tau nce lub zog kinetic thiab lawv cov nrawm nrawm
Cov kev hloov ntawm lub cev txawv ntawm cov tshuaj hloov pauv li cas muab ib qho piv txwv ntawm txhua tus?
Kev hloov tshuaj lom neeg tshwm sim los ntawm cov tshuaj tiv thaiv tshuaj, thaum lub cev hloov pauv yog thaum cov teeb meem hloov pauv tab sis tsis yog tshuaj lom neeg. Piv txwv ntawm kev hloov tshuaj lom neeg yog hlawv, ua noj, xeb, thiab rotting. Piv txwv ntawm kev hloov lub cev yog boiling, melting, khov, thiab shredding
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Peb qhov laj thawj tseem ceeb ntawm kev hloov pauv hloov pauv yog dab tsi?
Allele frequencies nyob rau hauv ib tug pej xeem yuav hloov vim plaub lub hauv paus zog ntawm evolution: Natural Selection, Genetic Drift, Mutations thiab Gene Flow. Kev hloov pauv yog qhov kawg ntawm cov alleles tshiab hauv cov noob caj noob ces. Ob ntawm cov txheej txheem tseem ceeb tshaj plaws ntawm kev hloov pauv hloov pauv yog: Natural Selection thiab Genetic Drift
