Iziphumo zovavanyo lweDNA kaTata zicacisiwe.
Uninzi lwabathengi bethu babuza malunga neziphumo zovavanyo lukaTata wethu kunye nendlela eziya kuboniswa ngayo. Ukubonisa umxholo onokulindela ukuwufumana kwingxelo, sibonise imizekelo yeengxelo zovavanyo lobutata-enye ibonisa iziphumo ezivumayo (Ukubandakanywa) kwaye enye ibonisa isiphumo esibi(ukungabandakanywa). Le mizekelo ibonisa uhlobo lolwazi oluya kubandakanywa kwingxelo yakho.
Iziphumo zovavanyo lobutata
Ingxelo ngeziphumo zovavanyo lobutata yakhiwe yangamacandelo amaninzi abalulekileyo, ngalinye libonisa ulwazi olubalulekileyo.
Ingxelo yokuqukumbela.
Eli candelo lelona candelo libaluleke kakhulu kwiSiphumo soVavanyo lwe-DNA kaTata. Nangona kunjalo, ngenxa yesigama esisemthethweni esisetyenzisiweyo, ngamanye amaxesha sinokubhida. Ingxelo ibonelela ngesigqibo esinye kwezimbini: ukuBandakanya nokuKhutshwa.
Nantsi inkcazo yezi ngxelo zimbini zesiphelo:
Ukuqukwa = Ukuba isiphelo sithi,"ayinakukhutshelwa ngaphandle njengotata webhayoloji," kuthetha ukuba indoda evavanyiweyo kusenokwenzeka ukuba ibe ngutata womntwana womntwana. Yonke idatha eqokelelwe kuvavanyo ixhasa kakhulu ubudlelwane bukatata.
Ukukhutshelwa ngaphandle = Ukuba isiphelo sithi,"ukhutshelwe ngaphandle njengotata webhayoloji," kuthetha ukuba indoda evavanyiweyo ayingoyise womntwana wemvelo. Idatha eqokelelwe kuvavanyo ayixhasi ubudlelwane bukayise.
Iimpawu zeGenetic Itheyibhile
I-LAB DNA Scientific yenza iimvavanyo zobutata ngokuphonononga ukuya kutsho kwiindawo ezili-16 ezahlukeneyo kwi-DNA yakho, ezibandakanya iimpawu zesini. Ezi ndawo, zaziwa njenge "STR loci," zidweliswe kwiingxelo zethu.
Kwindawo nganye kwezi ndawo, sihlalutya amacandelo athile e-DNA abizwa ngokuba yi "alleles." Kubalulekile ukuqaphela ukuba umntwana ngamnye ufumana ikopi enye yezi nxalenye zeDNA kumama wakhe kunye nenye kuyise.
Iteknoloji yethu yokuvavanya i-DNA ngokuchanekileyo ilinganisa ubude be-alleles kumthathi-nxaxheba ngamnye kwaye ithelekise kunye ne-alleles kayise ekutyholwa ngayo ukugqiba inani lemidlalo. Ukuba umama naye ubandakanyeka kuvavanyo, ii-alleles zakhe nazo ziyathelekiswa.
Kumzekelo wokuBandakanya okhankanywe ngaphambili, umntwana ovavanywayo uneseti ezimbini zeallele kwindawo nganye evavanyiweyo. Kule meko, kuyabonakala ukuba ubuncinane enye yezi iiseti ihambelana kunye alleles okutyholwa uyise kuzo zonke iindawo.
Kumzekelo wokuKhutshwa, nangona umntwana eneeseti ezininzi zee-alleles, ezinye zazo azihambelani nee-alleles zikayise ezityholwa, ebonisa ukunqongophala kokuhambelana kwezo ndawo ezithile.
What if, on a rare occasion, you receive 'Inconclusive' paternity test results.
‘Inconclusive’ means that no definite answer can be reached with the current samples, neither a ‘yes’ (‘not excluded’) nor a ‘no’ (‘excluded’).
​
There are two common reasons for an inconclusive DNA result in paternity testing:
1. The collected samples did not provide enough DNA, or
2. A definitive answer cannot be determined without including the biological mother's DNA in the test.
​
1. Insufficient DNA
If the samples sent to the lab yield fewer than 15 markers, it may be due to gentle swabbing, especially with newborns, or getting too much saliva instead of cheek cells. Even with weak samples, conclusive results can be achieved if the matches between the child and alleged father are strong. Otherwise, new samples may be needed for a conclusive result.
2. Including the Biological Mother in the Paternity Test
Since humans share 99% of their DNA, unique genetic differences are key in paternity testing. Sometimes, the differences between the child's and alleged father's DNA are not distinct enough for a conclusive answer. Including the biological mother's DNA can help clarify the results by eliminating half of the child's DNA, making it easier to determine paternity with a high probability or to exclude the alleged father.
