Umama, olindele amawele, uhlale enesithakazelo ukuthi izingane zakhe zizobonakala kanjani njengamaconsi amabili amanzi noma njengomfowenu nomzalwane noma njengomfowabo nodadewabo. Ngokungaqondile, akekho udokotela ongasho ukuthi, kodwa uma kunokwanele ukucacisa ukuthi imaphi amawele omama agqoke, kuzokwenzeka ukuba ucabange ukuthi kungenzeka ukuthi izingane zizobukeka kanjani ngaphandle.
Kunezinhlobo ezimbili zamawele, okubuye ahlukaniswe zibe yizicucu eziningana:
- amawele e-monozygotic;
- amawele e-dizygotic.
Amawele e-Monozygotic yimibungu evele ngemva kokuhlukaniswa kweqanda elilodwa. Kuye ngesikhathi sokuhlukaniswa, i-monozygotic: i-bihorionic, i-biamnotic, i-daimniotic ne-dichoric iyahluka. Njengomthetho, amawele e-monozygotic ayingqayizivele yobulili obufanayo futhi afana kakhulu.
Amawele e-dizygotic angamawele angamazwe. Izingane ezinjalo zithuthukisa ngayinye esikhwameni sabo, futhi zidla ngayinye kwi-placenta yayo. Bangaba ubulili obufanayo noma abesilisa nabesifazane. Kanti futhi ungahluka ngokuphelele nombala wamehlo nezinwele.
Izinhlobo zamawele we-monozygotic
Amawele e-diamial e-Monochorionic - lolu hlobo lweamawele luvame kakhulu ngamawele afanayo. Lawa mawele amiswa ngezinsuku ezingu-4-8 emva kokukhulelwa kweqanda, kodwa kuze kube mzuzu lapho i-zygote isetshenziselwa khona. I-Monochorion itholakala ukuthi lawa mawele adliwe kusuka ku- placenta eyodwa ngesikhathi sokukhulelwa . Lesi simo siyingozi nakakhulu kunaleso sakhiwo samawele, lapho umbungu ngamunye une-placenta yayo. Izingane ezinamandla ziyakunqanda ukuthuthukiswa komfowenu noma udadewabo, yingakho izingane ezinjalo zizalwa ngokwahlukana ngokulingana kwamagremu angu-500. Amawele kaDammonial asho ukuthi ingane ngayinye ikhula futhi ikhule esikhwameni sayo sesisu, kanti i-amniotic fluid evela komunye ayifinyeleli komunye. Lolu hlobo lweamawele lubizwa ngokuthi - amawele afanayo, azoba ngokobulili obufanayo futhi afane kakhulu.
Amawele e-Monochorion biamnotic afana namawele e-diamial e-monochorionic-i-placenta ejwayelekile, kodwa ngayinye e-sac yayo.
Amawele e-Monochorion amama-amniotic - lolu hlobo lwamaphanga lungenye yezinto eziyingozi kakhulu. Ukuhlukaniswa kwenzeka phakathi kwezinsuku ezingu-8 kuya kwezingu-12 kusukela ekukhuliseni, ngesikhathi lapho i-blastocyst isetshenziselwa khona i-endometrium. Yombili imibungu ikhona esikhwameni esifanayo se-amniotic futhi idliwe kusuka kwelinye i-placenta. Amawele anjalo avela eqanda elilodwa lesisu, futhi kungokwemvelo ukuthi bazoba nehlobo elifanayo legazi, isondo nesethi ye-chromosome. Izingane ezinjalo ziyoba nzima ukuqonda ngisho nabazali bazo.
Ingozi yukuthi ingane eyodwa ingase ixakeke emgqeni wesibili, futhi kungase kube nokunye okungavamile.
Uma kwenzeka ukuthi ukwehlukaniswa kweqanda kwenzeka ngemuva kosuku lwe-13 kusuka ekukhuliseni, ukuhlukana okuphelele akunakwenzeka. Ukukhanya kungase kubonakale amawele e-Siamese, kufakwe nganoma iyiphi ingxenye yomzimba.
Ukucindezeleka kokukhulelwa okuningi
Njengomthetho, ukukhulelwa okuphindwe kaningi kuqhubeka kunzima nakakhulu kunokukhulelwa kwe-singleton. Kulokhu, amawele we-monochorionic, angaphakathi
Kunoma yikuphi, ukugqoka amadoda amabili aphilayo ngaphansi kwenhliziyo ngesikhathi esisodwa kuyilungelo elikhulu nenkazimulo kumama. Futhi amaningi amawele aphile kahle, asevele azalwa, anika ithemba kuwo wonke umama olindele amawele.
