Hauv kev sib npaug ,ua p2 sawv cev qhov zaus ntawm homozygous genotype AA, q2 sawv cev qhov zaus ntawm homozygous genotype aa, thiab 2pq sawv cev qhov zaus ntawm heterozygous genotype Aa. Tsis tas li ntawd, cov sum ntawm allele frequencies rau tag nrho cov alleles ntawm qhov chaw yuav tsum yog 1, yog li p + q = 1.
Ib sab ntawm qhov no, vim li cas peb thiaj siv Hardy Weinberg kab zauv?
Hardy Weinberg tso cai rau kev suav ntawm allele zaus raws li cov pej xeem. Nws yog siv txhawm rau txheeb xyuas seb muaj pes tsawg tus alleles ntawm ib hom twg tuaj yeem muaj nyob hauv ib pawg neeg. Ib tug punnet square yuav siv sij hawm mus rau hauv tus account qhov tshwm sim uas cov xeeb ntxwv ntawm ib tug mating khub yuav qhia txog ib yam dab tsi.
Tom qab ntawd, lo lus nug yog, qhov sib npaug Hardy Weinberg siv rau dab tsi? Cov Hardy - Weinberg sib npaug yog lej kev sib npaug uas tau siv rau xam cov noob caj noob ces variation ntawm cov pejxeem ntawm kev sib npaug.
Yog li ntawd, koj ua li cas xam Hardy Weinberg equilibrium?
Cov Hardy - Weinberg Equation . Rau cov pej xeem hauv caj ces kev sib npaug : p + q = 1.0 (Cov lej ntawm cov zaus ntawm ob qho tag nrho yog 100%) nplooj ntawv no muaj tag nrho cov ntaub ntawv koj xav tau xam Allelic zaus thaum muaj ob qho sib txawv alleles.
Koj xam P thiab Q li cas?
los txiav txim q , uas yog qhov zaus ntawm recessive allele hauv cov pejxeem, tsuas yog siv lub hauv paus square ntawm q 2 0.632 (xws li 0.632 x 0.632 = 0.4). Yog li ntawd, q = 0.63. Txij li thaum p + q = 1, xa p yuav tsum yog 1 - 0.63 = 0.37. Tam sim no, los teb peb cov lus nug.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Qhov twg hauv qab no zoo tshaj plaws sawv cev rau qhov sib npaug molecular rau cov tshuaj tiv thaiv ntawm aqueous ammonia nrog sulfuric acid?
Nqe Lus Nug: Qhov Sib npaug Sib npaug rau Kev Ua Haujlwm Ntawm Aqueous Sulfuric Acid Nrog Aqueous Ammonia yog 2NH3 (aq) + H2SO4 (aq) --> (NH4) 2SO4 (aq) A
Dab tsi sawv cev rau qhov sib npaug ntawm kev sib npaug nuclear?
Ib qho kev sib npaug nuclear sib npaug yog ib qho uas cov lej ntawm cov lej loj (tus lej saum toj kawg nkaus hauv cov cim) thiab cov lej ntawm cov lej atomic sib npaug ntawm ob sab ntawm qhov sib npaug. Nuclear equation teeb meem feem ntau yuav muab xws li tias ib qho particle ploj lawm
Puas yog txhua qhov sib npaug sib npaug sib npaug?
Thawj qhov sib npaug sib npaug yog qhov tseeb yog tias nws muaj kev txuag kom muaj nuj nqis. Piv txwv li, qhov sib npaug sib cais yeej ib txwm muaj tseeb, txij li lub ntsiab lus lawv yog ntawm daim ntawv: M(y) + N(t) = 0, yog li ϕ(t, y) = A(y) + B(t) yog a khaws cia kom muaj nuj nqis
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
