Niam-me nyuam ob incompatibility ntawm vwm thiab D5S818 loci in kev xeem niam txiv.

Hais txog qhov no, d3s1358 txhais li cas ntawm kev kuaj DNA?

Piv txwv li, qee tus neeg yuav muaj 10 daim ntawv theej ntawm ATGC ntawm ib lub xaib thaum lwm tus yuav muaj 9 lossis 11 lossis xijpeem. Yog li ntawd yog qhov nws txhais tau tias thaum koj tau ib D3S1358 , 17/18 ib. Koj muaj 17 rov ua dua ntawm ib chromosome thiab 18 ntawm lwm qhov ntawm D3S1358 , ib qho chaw ntawm chromosome.

Ib qho tseem yuav nug, d1s1656 txhais li cas ntawm kev kuaj DNA? Locus (plural: loci) yog ib lo lus siv rau lub DNA cov cim uas yog kuaj thiab tshaj tawm rau koj Kev kuaj DNA tshwm sim. Txhua tus neeg muaj ob lub noob ntawm txhua tus cim. Ntawm koj DNA Test qhov tshwm sim koj yuav qee zaum nco ntsoov tias tsuas muaj ib tus lej teev tseg xwb. Qhov no txhais tau tias tias ntawm tus cim no ib tug neeg muaj ob qho tib si.

Tom qab ntawd, lo lus nug yog, th01 txhais li cas ntawm kev kuaj DNA?

Kev lig kev cai (lub sij hawm ncua = ob txhais tes ntawm xyoo) qhov chaw (loci, singular locus) nyob rau hauv lub genome tej zaum hu ua pseudo-genes yog li ua hauj lwm. Qhov chaw TSI 01 (ze ntawm cov noob rau tyrosine hydroxylase) txhais tau tias yog ib qho kev ncab ntawm 200 lub hauv paus ntawm 11p15.

Cov lej txhais li cas ntawm kev xeem niam txiv?

Versions ntawm a DNA kab zauv los yog ib tug noob hu ua "alleles". Cov no yog cov cim caj ces siv nyob rau hauv pog yawg Kev kuaj DNA . Cov kab ntawv cim "allele" ntawm lub DNA kuaj qhia muaj tus lej qhia txog ob qho alleles pom ntawm txhua qhov chaw (los yog ib qho tus lej yog tias lawv yog tib qhov loj).
