A dihybrid ntoo khaub lig yog a ntoo khaub lig ntawm ob tus neeg uas yog ob qho tib si heterozygous rau ob qhov sib txawv. Raws li ib piv txwv , cia saib cov txiv laum huab xeeb thiab hais tias ob qhov sib txawv peb tab tom tshuaj xyuas yog xim thiab qhov siab. Ib qho tseem ceeb allele H rau qhov siab thiab ib qho recessive allele h, uas ua rau ib tug dwarf pea cog.
Piv txwv li, Monohybrid thiab Dihybrid hla yog dab tsi?
A monohybrid ntoo khaub lig yog ib qho kev sim yug me nyuam ntawm P tiam (niam txiv tiam) cov kab mob uas txawv ntawm ib qho kev qhia zoo. Hom kev tshuaj ntsuam genetic no kuj yuav ua tau nyob rau hauv a dihybrid ntoo khaub lig , ib genetic ntoo khaub lig ntawm niam txiv tiam uas txawv ntawm ob yam.
Ib sab saum toj no, koj sau tus ntoo khaub lig Dihybrid li cas? Nws yog ib qho tseem ceeb uas koj ua raws li cov kauj ruam tsim nyog!
- Ua ntej koj yuav tsum tsim kom koj tus menyuam hla kev, lossis P1.
- Tom ntej no koj yuav tsum ua 16 square Punnett Square rau koj 2 yam koj xav hla.
- Cov kauj ruam tom ntej yog los txiav txim cov genotypes ntawm ob niam txiv thiab muab lawv cov ntawv los sawv cev rau cov alleles.
Kuj paub, dab tsi yog txhais los ntawm Dihybrid ntoo khaub lig?
dihybrid ntoo khaub lig . A dihybrid ntoo khaub lig piav qhia txog kev sib tw mating ntawm ob yam kab mob uas zoo ib yam hybrid rau ob qhov zoo. Lub cev hybrid yog ib qho uas yog heterozygous, uas txhais tau tias uas yog nqa ob lub alleles sib txawv ntawm ib txoj haujlwm caj ces, lossis locus.
Ib qho piv txwv ntawm Monohybrid ntoo khaub lig yog dab tsi?
Kev yug me nyuam ntev-stemmed pea cog nrog luv-stemmed pea cog yog ib qho piv txwv li ntawm tus ntoo khaub lig monohybrid . A ntoo khaub lig nruab nrab ntawm ob tsim heterozygous offsprings.

Dab tsi yog txuas graph piav nrog piv txwv?
Nyob rau hauv ib daim duab tiav, muaj ib ntug nruab nrab ntawm txhua khub ntawm vertices hauv daim duab. Qhov thib ob yog piv txwv ntawm ib daim duab txuas. Hauv kev sib txuas, nws tuaj yeem tau txais los ntawm txhua qhov vertex hauv daim duab mus rau lwm qhov vertex hauv daim duab los ntawm aseries ntawm ntug, hu ua txoj kev
Dab tsi yog geometric isomerism nrog piv txwv?
Geometric isomers yog cov molecules uas raug kaw rau hauv lawv txoj haujlwm spatial nrog kev hwm rau ib leeg vim yog ob daim ntawv cog lus lossis lub nplhaib qauv. Piv txwv li, xav txog ob lub molecules hauv qab no
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
