Ukuhlolwa kwe-DNA kwintandane ekhaya

Kwanakumbi kwiintsapho ezinempumelelo kakhulu, kunokuba kuyimfuneko ukufumanisa ukuba umntwana ungumhlobo wegazi lomntu ombona ukuba nguyise. Kwezinye iimeko, ngokuchaseneyo, kuyadingeka ukuba kusekwe umlinganiselo wobudlelwane ukuze kuqinisekiswe umntu ukuba umntwana akafuni ukuvelisa aze anikezele ngokwenene unyana wakhe okanye intombi.

Indlela yodwa yokuqinisekisa okanye ukuphika inyaniso yobudlelwane obusondeleyo kunye nokuhleleka okuphezulu ukuqhuba uvavanyo lwe- DNA oluphezulu kwintombi ekhaya okanye kwiklinikhi ekhethekileyo. Ukuphunyezwa kwale nkqubo kufuna ixabiso elaneleyo lemali kunye nemali ephawulekayo, ngoko ke akusiyo yonke imindeni inethuba lokujongana nayo.

Okwangoku, kukho ezinye iindlela ezithembekileyo ezinokuthenjelwa ngazo ukuba ngubani ongumntwana wengane, ngaphandle kokusebenzisa uphando olunzima kwaye luxabisa. Kule nqaku, siza kukuxelela indlela yokuseka umzali ngaphandle kokwenza uvavanyo lwe-DNA, kwaye indlela echanekileyo ngayo ingafumaneka ngayo ngale ndlela.

Indlela yokuchonga i-paternity ngaphandle kokuhlolwa kwe-DNA?

Kukho iindlela ezininzi ezikuvumela ukuba wazi u-paternity ngaphandle kokuhlolwa kwe-DNA, umzekelo, njenge:

1. Indlela elula ukubala umhla othe wenziwa ngumntwana, kwaye, ngokufanelekileyo, ukuchonga ukuba yeyiphi indoda ngaloo mini umama osemncinci walala ngesondo. Njengomthetho, "usuku lwe-X" lunjalo ngomhla we-14-15 emva kokuqala kwenyanga yokugqibela, ngoko akunzima ukuyifunda. Okwangoku, kufuneka kuqondwe ukuba nangomjikelezo oqhelekileyo wokuya esikhathini, i-ovulation inokuvela kwixesha elihlukeneyo, kwaye kwimeko yangexesha eliqhelekileyo leenyanga, akunakwenzeka ukucacisa ixesha eliphakamileyo ngaphandle kokusetyenziswa kweendlela ezizodwa. Ukongezelela, ukukhulelwa akusoloko kwenzeka ngokusemthethweni ngosuku lokuhamba. Ukususela kwiintsuku eziliqela ezandulela ukukhululwa kwe-ovule kwi-follicle nazo ziyakulungele ukuchumisa umzimba wesetyhini, kunzima nakakhulu ukuseka uyise wengane. Ekugqibeleni, awukwazi ukuphuhlisa abo bafazi abathi ngolunye usuku banokulala ngesondo kunye namadoda ahlukeneyo. Kubo, inkcazo yobazali kunye nale ndlela ayenzi nantoni na.
2. Kwakhona, ukuba uqonde ukuba umntu othile ungumntwana womntwana, unako, ngokuthelekisa iimpawu zotata nosana. Imiqondiso enjengombala wamehlo kunye neenwele, ukuma kwempumlo kunye neendlebe, ngokuqinisekileyo, kungabonakalisa ngokuthe ngqo ukuba ubudlelwane beentsapho phakathi kwabantu, kodwa awanakuthathi ngokubaluleka. I-crumb ingathatha yonke impawu yongaphandle kumama okanye nogogo, kodwa oku akuthethi ukuba uyise, ongakhange abukeke ngathi, akayena owakhe. Ngexesha elifanayo, kukho iimeko ezichasene nazo, xa abantu abafana nomnye abayizihlobo zegazi. Yingakho le ndlela ingathembekanga ngokupheleleyo.
3. Ukwenza uvavanyo lokubambisana ngaphandle kwe-DNA kunokwenzeka kwaye uqwalasele izinto ezinjengeqela legazi kunye neR Rh ye-father and child child. Ukuba impendulo engalunganga ifunyenwe kuphando olunjalo, ukunyaniseka kwayo kungathiwa ngumyalelo we-99-100%. Ukuba, ngenxa yolu vavanyo olunjalo, impendulo enhle ifunyenwe, ayinakuqwalaselwa njengento ebalulekileyo. Ngoko ke, ngokukodwa, ukuba umntwana osanda kuzalwa unalo uhlobo lwegazi olu-1, kunye no-ntatelo osisigxina 4, abayizihlobo zegazi ezinokwenzeka kakhulu. Ngelo xesha, uhlobo lwegazi lomama alukhathaleli.

Ewe, zonke ezi ndlela ziqikelele kakhulu. Ukuba intsapho inentswelo enkulu yokwenza ukuba ngubani oyenawo oyinyaniso kubantwana, kufuneka aqokelele izinto eziphilayo kunye nokuya kwi-laboratory ekhethekileyo ukuze afunde.
