Amawele amabili achazwa ngokuthi "... abasha ababili abazalwa ngokuzalwa nomama oyedwa." (I- Encyclopedia Britannica ). Qaphela ukuthi incazelo kuphela ibhekisela kumama. Kodwa kuthiwani ngobaba? Ingabe amawele angabawobaba abahlukile?
Amawele Amamababa Ahlukene
Njengoba ubuchwepheshe buye buthuthukisa ukunemba nokutholakala kokuhlolwa kofuzo, sekuye kwacaca ukuthi amawele angaba nobaba ababili abahlukene.
Isimo sisebenza kuphela kumawele omzimba (ama- dizygotic ) amawele, awafani namawele we- monozygotic , afomu kusuka enkambeni eyodwa / inhlanganisela yesilisa. Amawele e-Monozygotic angeke abe nobaba abahlukene.
Kodwa-ke, amawele angomfowabo angumphumela wokukhukhumeza, ukukhululwa kwamaqanda amaningi emjikelezweni owodwa. Ukuqhathaniswa kwemvelo kuchaza isimo lapho amaqanda ahlwanyelwa khona ngesidalwa esivela emithini ehlukene yokulala ngokocansi. Uma kwenzeka owesifazane ocansini nabalingani abahlukene, amawele angaba nobaba abahlukene. Ithimu elifanele ukuchaza lesi simo yi- superfecundation ye-heteropater .
Izibonelo zamadodakazi ahlukene nobaba
Lesi simo singase senzeke uma amawele ewumphumela wokunakekelwa kokuzala, isibonelo, icala likaKoen noTuen Stuart, abafana baseDutch ababengumphumela we-IVF (in vitro fertilization). Esikhathini sokuxuba ebhodini, imishini yayisetshenziswe kabili, okwenza umuthi womunye umuntu uhlanganiswe noyise.
E-New Jersey, umama wamawele wahlolwa ukuhlolwa komntwana lapho ecela usizo lomphakathi. Ngemuva kokuhlolwa ukuthi umlingani wakhe ubaba kuphela wamadodakazi akhe, wavuma ukuthi walala nomunye umuntu phakathi nesonto elifanayo lapho amawele akhe abelethwe khona.
Umama wamawele aseTexas uyavuma ukuthi ube nomunye nomunye umuntu lapho amawele akhe ekhulelwa.
Ukuhlolwa kwezingane kuveze ukuthi umdlwenguli wakhe wayenguyise wabafana ababili, kepha omunye umuntu wayengumama wezinye amawele.
