Le ukuhlolwa kwabazali is a ukuhlaziywa kofuzo okuvumela ukuqinisekisa izixhumanisi ze ubuzali begazi phakathi komuntu nengane yakhe. Siphinde sikhulume" Ukuhlolwa kwe-DNA ".

Ivamise ukucelwa ezinqubweni zomthetho (kuyalelwa ijaji lenkantolo yomndeni), kodwa isetshenziswa kaningi, njengoba manje sekulula ukuthola izinsiza zokuhlola ngokukhululeka ku-inthanethi. Nokho, lo mkhuba usalokhu ungekho emthethweni eFrance.

Ngokocwaningo olwanyatheliswa kuyi-Lancet ngo-2006, cishe esimweni esisodwa kwezingama-30, ubaba omenyezelwe akayena ubaba wengane.

Uma kwenzeka "ukumangalelana kwabazali", okusho ukuthi lapho isixhumanisi somzali siphikisana noma ubaba engazange abone ingane, isibonelo, umzali angase abangele isahlulelo. Lokhu kungenziwa ngomongo wezenzo ezimbalwa zomthetho:

• ucwaningo lobaba (luvuleleke kunoma iyiphi ingane engaziwa ngubaba wayo)
• ukubuyiselwa kokucatshangelwa kobaba (ukufakazela ububaba bomlingani womshado uma kwenzeka isehlukaniso, isibonelo)
• Inselelo yobaba
• izenzo kumongo wokulandelana
• izenzo ezihlobene nokufuduka, njll.

Khumbula ukuthi ubuzali ihlotshaniswa nezibopho ezithile, ezindabeni zesondlo noma ifa, isibonelo. Ngakho, izicelo zokuhlolwa kobaba ngokuvamile zivela kwabesifazane abafuna isondlo kowayeshade naye, kobaba abafisa ukuthola amalungelo okuvakashelwa noma okukhulisa ingane, noma abafisa ngisho nokugwema izibopho zabo ngoba besola ukuthi abahlobene ngokwemvelo nengane. E-France, amalabhorethri athile kuphela agunyazwe uMnyango Wezobulungiswa ukwenza lobu buchwepheshe, ngemvume yabantu abahilelekile (kungenzeka njalo ukwenqaba ukuzithoba ekuhlolweni).

Khumbula ukuthi ukuthengwa kwezivivinyo ku-inthanethi akukho emthethweni e-France futhi kujeziswa ngezinhlawulo ezinzima. Kwenye indawo eYurophu naseNyakatho Melika, ukuthengwa kusemthethweni.

Namuhla, ukuhlolwa kobaba kuyenziwa ezimweni eziningi kakhulu kusuka ku- ama-swabs omlomo. Ukusebenzisa i-swab (i-cotton swab), hlikihla ingaphakathi lesihlathi ukuze uqoqe amathe namaseli. Lokhu kuhlola okusheshayo, okungahlanyisi bese kuvumela ilebhu ukuthi ikhiphe i-DNA futhi iqhathanise “izigxivizo zeminwe zofuzo” zalabo abahililekile.

Ngempela, uma izakhi zofuzo zabo bonke abantu zifana kakhulu komunye nomunye, kukhona zonke izinhlobo ezincane zofuzo ezifanayo ezibonisa abantu ngabanye futhi ezidluliselwa enzalweni. Lezi zinhlobonhlobo, ezibizwa ngokuthi "ama-polymorphisms", zingaqhathaniswa. Cishe omaka abayishumi nanhlanu banele ngokujwayelekile ukusungula ukuxhumana komndeni phakathi kwabantu ababili, ngokuqiniseka okusondele ku-100%.
