Kule mihla, ukuzalwa kwamawele kuqheleke kakhulu kunangaphambili. Mhlawumbi unamawele kusapho lwakho okanye phakathi kwabahlobo bakho. Xa ufumanisa ukuba unamawele, uziva uvuyo olukhulu kunye nomdla omncinci. Phantse wonke umntu uyazi kuphela ngamawele afanayo namawele angamaqabane. Kodwa kukho okungakumbi emva kwezi ntlobo zimbini. Kulungile, masithethe ngehlabathi elimangalisayo lamawele ngendlela elula.
Iindlela ezimbini eziphambili zokukhulelwa amawele
Zimbini iindlela eziphambili amawele anokukhulelwa ngazo. Oogqirha babiza la mawele ngokuthi "yiDizygotic" kunye "yiMonozygotic". Ngokwendlela eqhelekileyo, la ngamawele ahlukeneyo kunye namawele afanayo.
- Amawele anobuzalwana/angenasibeleko: Oku kwenzeka xa amaqanda amabini ekhutshwa kwizibeleko zikamama ngaxeshanye aze aqhanyiswe sisidoda esibini esahlukileyo kutata. Ngamanye amazwi, kufana nokumitha okubini okwenzeka ngaxeshanye.
- Amawele afanayo/angenawo umzali omnye: Oku kwenzeka xa iqanda elinye, elivundiswe sisidoda esinye, liqhekeka libe mabini kwiiveki zokuqala ezimbalwa zokukhulelwa . Oku kungenxa yokuba abantwana ababini babonakala befana kuba umbungu omnye waqhekeka kubini.
Okwangoku, unyango lokuzala, ingakumbi ubuchwepheshe obufana ne-IVF, ngamanye amaxesha lunokubangela amawele ahluke kancinci kwezi ndlela zesintu. Oogqirha bathi oku "kukwaluka okungaqhelekanga." Ezi aziqhelekanga kakhulu.
Ngoobani la mawele afanayo? (Amawele e-Monozygotic)
La ngamawele afanayo esiwaziyo sonke. Malunga nesithathu kwisithathu samawele onke emhlabeni angamalungu olu hlobo.
Njengoko benditshilo ngaphambili, aba bantwana badalwe ngokuchumisa iqanda elinye ngesidoda esinye, emva koko i-embryo yahlulwe kabini. Ngoko ke, ulwazi lwabo lwemfuza, oko kukuthi, i-'DNA' yabo, ifana nge-100% . Yiyo loo nto bebonakala kwaye bevakalelwa ngendlela efanayo.
Eyona nto ibalulekileyo kukuba la mawele "angumhlobo omnye" ahlala engabantu besini esinye . Oko kukuthi, omabini ngamantombazana okanye omabini ngamakhwenkwe.
Ngamanye amaxesha la mawele anokwabelana ngesingxobo esinye se-amniotic esibelekweni. Oku kugqitywa lixesha apho umbungu uqhekeka khona. Enye into emangazayo kukuba amanye amawele afanayo afana "nemifanekiso yesipili." Oko kukuthi, okukwicala lasekunene lomntwana omnye kuyafana nokukwicala lasekhohlo lomntwana omnye. Umzekelo, ukuba omnye usebenzisa isandla sasekunene, omnye usenokuba usebenzisa isandla sasekhohlo. Enyanisweni, isizathu sokuba umbungu oqhagamshelweyo wahlukane kubini kuseyimfihlakalo kumayeza.
Kuthekani ngamawele abonakala ahlukile? (Amawele ane-dizygotic)
Olu lolona hlobo luqhelekileyo lwamawele. Malunga nesibini kwisithathu samawele onke angalolu hlobo. Sikwawabiza ngokuba " ngamawele angootata".
Kulapho amaqanda amabini ahlukeneyo aqhanyiswa khona sisidoda esibini esahlukileyo. Ke ngoko, aba bantwana bane-50% kuphela yolwazi olufanayo lwemfuza (i-DNA). Ukuchaneka, bafana nabazalwana ababini abaqhelekileyo abazalwa ngamaxesha ahlukeneyo .
Ngenxa yale nto,
- Akunyanzelekanga ukuba zifane.
- Akunyanzelekanga nokuba babe ngabantu besini esinye. Oko kukuthi, ukuba kukho amawele angamantombazana nenkwenkwe , ngokuqinisekileyo angamawele "aneDizygotic".
- Zinee-placentas ezahlukeneyo kunye nee-amniotic sacs ezahlukeneyo kwisibeleko.
Ungazi njani ngokuqinisekileyo ukuba amawele afana okanye ahlukile?
Le yingxaki ebanayo abazali abaninzi.
- Ukuba amawele akho yintombazana nenkwenkwe , akukho ngxaki. Ngokuqinisekileyo angamawele ahlukeneyo .
- Kodwa ukuba bobabini bangabantu besini esifanayo , oko kukuthi, bobabini bangabafana okanye amantombazana, ibali liyinkimbinkimbi ngakumbi.
Ii-ultrasound scans ngexesha lokukhulelwa, ingakumbi emva kweeveki ezili-14, zinokunika oogqirha umbono othile nge-placenta yomntwana. Kodwa azichanekanga ngokupheleleyo.
Eyona ndlela ichanekileyo nethembekileyo yokufumanisa ukuba amawele afana na (`Monozygotic`) okanye i-dizygotic (`Dizygotic`) kukwenza uvavanyo lwe-`DNA` emva kokuba abantwana bezelwe.
Ngamanye amaxesha, xa abantwana bezalwa, bajonga i-placenta baze bathi, "La ngamawele afanayo," kodwa njengoko abantwana bekhula, baqala ukubonakala bahlukile. Kusenokuba njalo nangayiphi na indlela. Ngoko ke, ukuba ufuna ukwazi ngokuqinisekileyo, eyona nto ingcono onokuyenza kukufumana uvavanyo lwe-'DNA'.
| Uhlobo lwamawele | Izinto ezichaphazela amathuba okuba namawele |
|---|---|
| Amawele afanayo (i-Monozygotic) | Oku kwenzeka ngequbuliso. Amathuba okuba umfazi abe namawele afanayo amalunga ne-1 kwi-250. Izinto ezifana nemfuza, ubudala, kunye nohlanga azichaphazeli oku. |
| Amawele ane-dizygotic | Zininzi izinto ezinokuchaphazela oku:

Iintlobo zamawele ezingaqhelekanga kakhulu ezimangalisayo ukuva ngazo
Mhlawumbi awukaze uve ngezi zinto kuba aziqhelekanga kakhulu.
- Amawele afanayo `(Sesquizygotic)`: Oku kwenzeka xa iqanda elinye lixutywe sisidoda esibini. Oku kunqabile kakhulu, njengoko ngesiqhelo akukho zimbungu zenziwe ngolu hlobo ezisindayo. Aba bantwana banokuba ne-DNA yabo ephakathi kwe-50% ne-100%. Okumangalisayo kukuba, olu hlobo lwamawele lunokuba ngabesini esahlukileyo.
- I-Vanishing Twin Syndrome: Olu asilohlobo lwamawele, kodwa yinto eyenzekayo ngexesha lokukhulelwa. Xa kukhulelwa amawele amabini, elinye lala mawele liyayeka ukukhula kwaye lifunxwe emzimbeni kamama okanye kwelinye i-fetus.
- I-Fetus-in-fetu: Oku kuthetha "i-fetus ngaphakathi kwi-fetus." Le yimeko yamawele anesifo esibangelwa yi-parasitic. I-fetus engakhulanga yelinye iwele ifumaneka emzimbeni womntwana ophilileyo. Oku kunqabile kakhulu.
- Ukuzala (Superfetation) kunye nokuzala (Superfecundation): Ezi zizinto ezingaqhelekanga kakhulu. 'Ukuzala (Superfecundation)' kukwenzeka kokumitha kwakhona ngelixa umfazi sele ekhulelwe. 'Ukuzala (Superfecundation)' kukuzala amaqanda amabini akhutshwe ngexesha elifanayo lomjikelo wokuzala ngesidoda esivela kumadoda amabini ahlukeneyo. Kuninzi okusafunyaniswa ngokwesayensi ngezi zinto.
Musa ukukhathazeka ngezi ntlobo zingaqhelekanga. Kuba amathuba okuba ezi ntlobo zezifo aphantsi kakhulu. Amaxesha amaninzi, sidibana namawele ezi ntlobo zimbini ziphambili esithethe ngazo ngaphambili.
Umyalezo Wokuya Ekhaya
- Iintlobo ezimbini eziphambili zamawele yi- monozygotic/identical kunye ne -dizygotic/fraternal twins.
- Amawele afanayo akhiwa xa imveku enye yahlukana kabini, kwaye i-DNA yabo ifana nge-100%. Amawele azalwa ngamaqabane akhiwa xa amaqanda amabini ahlukeneyo exutywa sisidoda esibini esahlukileyo. Afana nabazalwana abaqhelekileyo.
- Eyona ndlela yokwazi ngokuchanekileyo ngokupheleleyo ukuba amawele esini esifanayo afana nawaphi na kukwenza uvavanyo lwe-DNA emva kokuba abantwana bezelwe.
- Kukho nezinye iintlobo zamawele ezingaqhelekanga kakhulu, kodwa azixhaphakanga kakhulu. Ngoko ke ungakhathazeki kakhulu ngaloo nto.
- Ukuba unenkxalabo malunga namawele okanye naziphi na ezinye iingxaki ngexesha lokukhulelwa kwakho, thetha ngokukhululekileyo nogqirha wakho ngayo loo nto.
