Co - kev tswj hwm yog ib hom uas tsis yog-Mendelian qub txeeg qub teg uas pom cov yam ntxwv qhia los ntawm cov alleles kom sib npaug hauv cov phenotype. Co - kev tswj hwm yuav qhia ob qho tib si alleles sib npaug es tsis txhob sib xyaw ntawm qhov zoo li tau pom hauv tsis tiav dominance.
Hauv qhov no, dab tsi yog kev sib koom ua ke?
Qee cov alleles muaj zog sib npaug thiab tsis tau npog los ntawm lwm tus. Thaum ob qho alleles nyob, lawv ob leeg tau qhia hauv phenotype. Codominance, yog qhov xwm txheej uas ob qho tib si alleles sib npaug sib npaug thiab ob qho alleles pom nyob rau hauv hybrid genotype. Ib qho piv txwv ntawm codominance muaj nyob rau hauv qaib.
Dhau li saum toj no, dab tsi yog co dominance qub txeeg qub teg? Codominance Kev Codominance yog ib qho kev sib raug zoo ntawm ob lub gene. Cov tib neeg tau txais ib qho qauv ntawm cov noob, hu ua allele, los ntawm txhua tus niam txiv. Yog tias alleles txawv, cov tseem ceeb allele feem ntau yuav raug qhia, thaum cov nyhuv ntawm lwm cov allele, hu ua recessive, yog npog.
Ib yam li ib tug yuav nug, Codominance muab piv txwv li cas?
Thaum ob lub alleles rau ib qho kev zoo sib npaug sib npaug nrog tsis yog recessive los yog dominant, nws tsim codominance . Piv txwv ntawm codominance suav nrog tus neeg muaj ntshav hom AB, uas txhais tau hais tias ob qho tib si A allele thiab B allele tau qhia sib npaug.
Qhov txawv ntawm Codominance thiab tsis tiav dominance yog dab tsi?
Hauv ob qho tib si codominance thiab tsis tiav dominance , ob leeg alleles rau ib tug zoo tseem ceeb . Hauv codominance ib tug neeg heterozygous nthuav qhia ob qho tib si ib txhij yam tsis muaj kev sib xyaw. Hauv tsis tiav dominance tus neeg heterozygous sib xyaw ob qhov zoo.

Vim li cas txoj kev sib koom tes sib koom ua ke tseem ceeb?
Kev kawm Interdisciplinary tso cai rau kev sib txuas ntawm cov tswv yim thiab kev sib txuas ntawm cov yam ntxwv los ntawm ntau yam kev qhuab qhia. Nyob rau tib lub sijhawm nws hais txog cov tub ntxhais kawm qhov sib txawv ntawm tus kheej thiab pab tsim cov txuj ci tseem ceeb, hloov pauv tau
Kev sib koom siab thiab kev sib txawv hauv biology yog dab tsi?
Evolution yog kev sib koom ua ke ntawm biology. Nws piav txog kev sib koom siab thiab ntau haiv neeg ntawm lub neej. 1) Cov xeeb leej xeeb ntxwv los ntawm cov poj koob yawm txwv piav txog kev sib sau ntawm lub neej. 2) kev sib koom ua ke ntawm lub neej = cov khoom muaj sia sib koom ua ke thiab cov qauv ntawm tes (DNA, RNA thiab cell membrane)
Dab tsi yog cov kev siv ntawm kev sib koom ua ke?
Ib daim ntawv thov tseem ceeb ntawm kev sib koom ua ke yog lawv siv los ua cov catalysts, uas pab hloov cov tshuaj tiv thaiv kab mob. Qee qhov nyuaj hlau catalysts, piv txwv li, ua lub luag haujlwm tseem ceeb hauv kev tsim cov polyethylene thiab polypropylene
Dab tsi yog qhov kev pabcuam kev sib koom tes?
Kev Pabcuam Solidarity yog dab tsi? Ib qho kev pabcuam uas cov neeg tuaj koom zaum kaum ob rau ib lub rooj, hloov cov txiv neej thiab poj niam. Tom qab ntawd lawv noj strawberry ice cream nrog soma thiab noj ib ntsiav tshuaj soma, ua hauj lwm lawv tus kheej mus rau hauv ib tug frenzy ntawm exultation, thiab xaus nyob rau hauv kev sib deev orgy
Dab tsi yog qhov sib txawv ntawm qhov muaj feem cuam tshuam thiab kev sib koom ua ke?
Hais lus dav dav, qhov sib koom ua ke yog qhov tshwm sim ntawm ob yam * tshwm sim ua ke: piv txwv li, qhov tshwm sim uas kuv ntxuav kuv lub tsheb, thiab nag los. Qhov xwm txheej tshwm sim yog qhov tshwm sim ntawm ib yam tshwm sim, muab tias lwm yam tshwm sim: piv txwv li, qhov tshwm sim uas, muab tias kuv ntxuav kuv lub tsheb, los nag
