Uhlalutyo lomgaqo-DNA kuba Y-chromosome DNA Diagnostics Iziko ngu ngokwenza yokufumana phandle ukuba ezimbini okanye ngaphezulu abantu kuba biological budlelwane kwi-macala zabo uyise. Kubalulekile eyodwa kwi-njalo ugqatso kwi-paternity, apho distinguishes uhlalutyo ngokobuhlanga ngelize-ubawo haplogroup ye-descent kuwe isiseko kwindlela yakho DNA kuphelaUhlalutyo lomgaqo-uthelekiso ka-Y-chromosome zingasetyenziswa kwi-ubungqina ka-usapho budlelwane xa alleged uyise a indoda ayikho kuba uhlalutyo kwi-paternity kunye nezinye i-DNA ukuvavanywa usapho ubudlelwane phakathi aziyi kusetyenziswa kule meko. Hereditary unyana wakhe Y chromosome ukusuka uyise, kwaye chromosome ukuba kuya kuphunyezwe abancinane okanye akukho tshintsho Ngenxa kunjalo oku, Y chromosome ye-indoda iya kuba inkangeleko kwaye thelekisa ukugqiba ukuba umntu ubani biological budlelwane kwi-macala zabo uyise. Amadoda kunye kubudlelwane biological icala, uyise wabo uya bonisa identical Y-STR zabucala, xa amadoda akukho ngokunxulumene uza bonisa eyodwa Y-STR yabucala. Qaphela: Xa uhlalutyo lomgaqo-uthelekiso ka-Y-chromosome unako ukwenza determination ukuba indoda nganye nganye ngu-enxulumene icala kabawo, akekho kubonisa ukuba uhlobo budlelwane ukuba babe ngonaphakade waba ngutata, uncle, utatomkhulu, njalo-njalo.
