Txuas pob ntseg : Lus dab neeg
dawb pob ntseg feem ntau yog siv los qhia txog qhov yooj yim noob caj noob ces . Cov lus dab neeg yog qhov ntawd pob ntseg tuaj yeem muab faib ua ob pawg meej, dawb thiab txuas , thiab hais tias ib lub noob tswj qhov zoo, nrog rau allele dawb pob ntseg ua tus tseem ceeb. Tsis yog ib feem ntawm cov lus dab neeg tsis muaj tseeb.
Nyob rau hauv no hais txog, yog txuas earlobes dominant los yog recessive?
Yog lawv txuas ncaj qha mus rau sab ntawm lub taub hau, lawv txuas earlobes . Qee cov kws tshawb fawb tau tshaj tawm tias qhov zoo li no yog vim muaj tib lub noob uas tsis sib txuas pob ntseg yog tseem ceeb thiab txuas earlobes yog rov ua dua.
Ib yam li ntawd, pes tsawg feem pua ntawm cov pej xeem tau txuas pob ntseg? 18 = 0.99 lossis 99 feem pua ntawm no pej xeem muaj tsis sib cuag pob ntseg . Lub phenotype recessive = 0.01 los yog 1 feem pua ntawm no cov pejxeem tau txuas earlobes.
Tsis tas li ntawd, vim li cas qee cov neeg earlobes txuas?
" txuas "zoo li pob ntseg feem ntau nthuav tawm ua piv txwv ntawm ib qho yooj yim "ib noob - ob alleles" Mendelian qhov zoo ntawm tib neeg, pob ntseg tsis txhob poob zoo nyob rau hauv ob pawg; muaj ib tug tas mus li ntau yam ntawm ib tug huab mus rau lwm yam, tawm tswv yim lub hwj chim ntawm ob peb noob.
Dab tsi yog genotype rau earlobes txuas?
Tus neeg nrog Ee genotype yog heterozygous rau qhov zoo, qhov no, dawb pob ntseg . Ib tus neeg yog heterozygous rau qhov zoo thaum nws muaj ob hom allelic sib txawv ntawm ib qho gene. Yog koj muaj txuas earlobes , koj muaj ob tug alleles rau qhov zoo. Cov noob caj noob ces tsis tshua muaj feem yuav tau txais txiaj ntsig.

Plaub lub pas dej hiav txwv loj yog dab tsi yog cov bass txuas nrog?
Plaub lub hauv paus dej hiav txwv tseem ceeb yog cov Pacific, Atlantic, Indian, thiab Arctic Oceans. Dej hiav txwv Pacific, uas nyob txog ib feem peb ntawm lub ntiaj teb nto, muaj lub phiab loj tshaj plaws. Nws lub phiab kuj muaj qhov tob tshaj qhov nruab nrab ntawm kwv yees li 14,000 ko taw (4,300 meters)
Puas yog tus nplaig dov txuas ntxiv lossis tsis txuas ntxiv?
Tus nplaig dov yog ib qho piv txwv ntawm kev hloov pauv tsis tu ncua: koj tuaj yeem yob koj tus nplaig lossis koj ua tsis tau. Cov yam ntxwv uas qhia kev hloov pauv tas mus li feem ntau yog tshwm sim los ntawm txoj kev nyuaj, lossis ntau yam, cov qauv ntawm cov qub txeeg qub teg uas muaj ntau yam sib txawv ntawm cov noob thiab cov yam ntxwv hauv ib puag ncig (piv txwv li, kev noj haus)
Puas yog cov kab sib txuas ua pov thawj cov kab sib txuas?
Thawj yog yog tias cov ces kaum sib thooj, cov ces kaum uas nyob rau tib lub ces kaum ntawm txhua qhov kev sib tshuam, yog sib npaug, ces cov kab sib npaug. Qhov thib ob yog yog tias qhov sib txawv sab hauv lub kaum sab xis, cov ces kaum uas nyob rau sab nraud ntawm lub transversal thiab sab hauv cov kab sib npaug, sib npaug, ces cov kab sib npaug
Cov earlobes txuas tau li cas?
Yog tias lawv txuas ncaj qha rau sab ntawm lub taub hau, lawv txuas nrog pob ntseg. Qee cov kws tshawb fawb tau tshaj tawm tias qhov kev coj cwj pwm no yog vim muaj tib lub noob rau cov pob ntseg uas tsis tau txuas nrog lub ntsej muag yog qhov tseem ceeb thiab cov pob ntseg uas txuas nrog yog qhov tsis zoo. Qhov loj thiab cov tsos ntawm cov lobes kuj tau txais txiaj ntsig zoo
Puas yog cov kab sib txuas sib txuas hauv hyperbolic geometry?
Hauv hyperbolic geometry, muaj ob hom kab sib npaug. Yog hais tias ob kab tsis sib tshuam nrog tus qauv ntawm hyperbolic geometry tab sis lawv sib tshuam ntawm nws tus ciam teb, ces cov kab yog hu ua asymptotically parallel lossis hyperparallel
