Yuav kom cov pej xeem nyob hauv Hardy-Weinberg equilibrium, lossis lub xeev tsis hloov pauv, nws yuav tsum ua raws li tsib qhov kev xav loj:
- Tsis muaj kev hloov pauv . Tsis muaj cov alleles tshiab yog tsim los ntawm kev hloov pauv , tsis yog noob duplicated lossis deleted.
- Random mating.
- Tsis muaj gene flow.
- Cov pejxeem loj heev.
- Tsis muaj natural xaiv .
Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog ib qho xwm txheej uas yuav tsum tau ntsib rau cov pej xeem kom muaj kev sib npaug ntawm caj ces?
Tus qauv Hardy-Weinberg tau hais tias cov pej xeem yuav nyob twj ywm ntawm caj ces sib npaug ntev li tsib yam xwm txheej: (1) Tsis muaj kev hloov pauv hauv DNA, (2) Tsis muaj kev tsiv teb tsaws chaw, (3) Cov pej xeem loj heev, (4) Random mating , thiab (5) Tsis muaj kev xaiv ntuj.
Tsis tas li ntawd, Hardy Weinberg equilibrium siv rau dab tsi? Hauv kev tshawb nrhiav noob caj noob ces, cov Hardy - Weinberg kev sib npaug tuaj yeem yog siv rau ntsuas seb qhov kev soj ntsuam genotype zaus hauv cov pej xeem sib txawv ntawm cov zaus kwv yees los ntawm qhov sib npaug.
Ib yam li ntawd, tib neeg nug, Hardy Weinberg lub hauv paus ntsiab lus ntawm caj ces equilibrium yuav siv los txiav txim seb cov pejxeem no puas hloov zuj zus mus?
Hardy - Weinberg Txoj Cai ntawm Equilibrium Cov Hardy - Weinberg txoj cai xeev uas a cov pejxeem allele thiab genotype zaus yuav nyob tas li nyob rau hauv qhov tsis muaj evolutionary mechanisms. Thaum kawg, lub Hardy - Weinberg txoj cai qauv a pej xeem tsis muaj evolution nyob rau hauv cov xwm txheej hauv qab no: tsis muaj kev hloov pauv.
Dab tsi yog qhov zaus ntawm qhov tseem ceeb allele?
Cov zaus ntawm cov dominant allele hauv cov pejxeem. Teb: Cov zaus ntawm qhov tseem ceeb (ib txwm) allele hauv cov pejxeem (p) tsuas yog 1 - 0.02 = 0.98 (los yog 98%). Qhov feem pua ntawm cov neeg heterozygous (cov neeg nqa khoom) hauv cov pej xeem.

Yuav ua li cas yuav tsum tshwm sim rau transcription ntawm lac operon?
Dab tsi ntawm cov hauv qab no yuav tsum tshwm sim rau kev hloov pauv ntawm cov noob lac operon coj qhov chaw? Cov protein repressor khi rau DNA molecule, thiab RNA polymerase poob. Lactose raug tshem tawm ntawm lub cev. Lub repressor protein poob tawm ntawm DNA molecule, thiab RNA polymerase khi rau tus txhawb nqa
Dab tsi yuav tsum tshwm sim rau ib tus neeg los qhia txog qhov zoo ntawm polygenic?
Los qhia txog qhov zoo ntawm polygenic: A) cov noob yuav tsum cuam tshuam nrog ib puag ncig. ob peb lub noob yuav tsum ua ua ke. C) Ntau yam kev hloov pauv yuav tsum tshwm sim hauv tib tsev neeg
Tam sim ntawd yuav siv dab tsi yog tias koj cov khaub ncaws raug hluav taws lossis yog tias muaj tshuaj lom loj tshwm sim ntawm koj cov khaub ncaws?
Tam sim ntawd yuav siv dab tsi yog tias koj cov khaub ncaws raug hluav taws lossis yog tias muaj tshuaj lom ntau tshwm sim ntawm koj cov khaub ncaws? Koj mus ncaj qha rau da dej kev nyab xeeb thiab sawb ntawm tag nrho koj cov khaub ncaws
Yuav ua li cas cov khoom siv caj ces hauv txhua lub xov tooj tshiab tsim los ntawm kev faib tawm ntawm tes sib piv nrog cov khoom siv caj ces hauv lub xov tooj qub?
Mitosis tshwm sim nyob rau hauv ob lub nuclei uas zoo tib yam rau thawj nucleus. Yog li, ob lub hlwb tshiab tsim tom qab kev faib tawm ntawm tes muaj tib yam khoom siv caj ces. Thaum lub sij hawm mitosis, chromosomes condense los ntawm chromatin. Thaum saib nrog lub microscope, chromosomes pom nyob rau hauv lub nucleus
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
