Umkhuba ongaziwa we amawele izibuko Kuyiqiniso ukuthi kwenzeka ngokungajwayelekile phakathi kwamaphesenti angama-25 wamacala. Igama elithi "isibuko" lisetshenziselwa umphumela wokuthi izingane ezizalwa zifana ngokuphelele, njengamaconsi amabili amanzi.
Bangabantwana abazalwa beyibo amawele afanayo, okungukuthi, zidalwe ngaphakathi kwesibeletho ngenxa yokuvundiswa kweqanda nesidoda esisodwa. Zakha i-zygote futhi yona ihlukana ibe imibungu emibili. Ukuze uthole imininingwane eyengeziwe sizohlaziya ukuthi yiziphi izici ezengeziwe abanazo.
Anjani ama-cufflink esibuko?
Njengoba sesike sasho, bangamawele afanayo. Bangamawele afanayo noma e-monzygotic. Banesici esiyingqayizivele, sokuthi badaliwe ngenxa yokuvundiswa kweqanda nesidoda, bese yenza i-zygote bese ihlukana ibe imibungu emibili. Ngesikhathi esifanayo banesinye isici esihle, la mawele athuthuka futhi babelana nge-placenta efanayo nesaka le-amniotic.
Kungani behluke kwabanye abakhulelwe abangamawele?
Ukukhulelwa kwamawele kungahlukaniswa komunye kuya kokunye ngesikhathi i-zygote idala ukuhlukana kwayo. Kunamacala ahlukene:
Amawele angefani noma e-dizygotic
Babizwa ngamawele. Kuwumphumela wemibungu emibili esiswini, kodwa kulokhu owesifazane uyaxosha ama-ovules amabili futhi womabili avundiswa isidoda esihlukene. Kulokhu sikhuluma ngabantwana ababili abakhule esibelethweni esisodwa futhi abangazange bahlanganyele i-amniotic sac, noma i-placenta, futhi abanalo ufuzo olufanayo. Ababili kwabathathu abakhulelwayo abanengi bangalolu hlobo.
Amawele afanayo noma e-monozygotic
Yibo asebechaziwe. Kulapho iqanda selivundisiwe nalapho i-zygote ihlukana kabili. Lapho kuhlukaniswa, imibungu emibili idalwa enomthwalo wofuzo ofanayo.
- I-Bichorial ne-diamniotic. I-zygote ihlukana ezinsukwini ezintathu emva kokuvundiswa. Kulokhu, imibungu eyakhiwe yondliwa yi-placenta yayo futhi ikhula esakeni layo le-amniotic.
- I-Monochorionic ne-monoamniotic. Ukuhlukaniswa kwe-zygote kwenziwa kamuva kakhulu, phakathi kosuku lwesikhombisa nolweshumi nantathu lokuvundiswa. Lapha imibungu yabelana nge-placenta efanayo kanye nesaka le-amniotic elifanayo. Yilapho amawele esibuko angafakwa khona, nakuba enza isici sokuhlukanisa phakathi kosuku lwesishiyagalolunye nolweshumi nambili ngemva kokuvundiswa. Kulokhu, ukuhlukaniswa kwe amaseli afana ncamashí, elinye kwesokunxele nelinye kwesokudla.
Kuleli qophelo kungase kube icala Iwele elinyamalalayo, lapho omunye wemibungu ungaqedi ukukhula futhi umuntshwa ngumama, i-placenta noma imbala omunye umfowabo. Leli cala laziwa uma kwenziwa i-ultrasound yejwayelo ngenyanga yesithupha yokukhulelwa futhi kubonakale ukuthi kunemibungu emibili noma ngaphezulu. Kamuva, kwenye i-ultrasound elandelayo, enye yazo iyanyamalala futhi enye iyaqhubeka nokukhula ngaphandle kwenkinga.
Izici ezingavamile ze-mirror cufflinks
Lezi zingane zibhekwa ngezici zazo ezingavamile lapho zizalwa. Izitho ezakhiwe emizimbeni yazo zingadalwa ngendlela ephambene. Kokubili inhliziyo, isibindi kanye nobende kubekwe kusuka komunye kuya komunye ezinhlangothini ezihlukene zemizimba yazo. ucingo "i-situs inversus" futhi yenzeka ngokungavamile, icala elilodwa kuphela kwabayi-10.000. Ngisho nomphumela wesibuko ungadalwa ngezici ezingasho lutho njengezinwele, izimpawu zokuzalwa noma ama-moles.
Idatha ibuye yachazwa kabanzi lapho kubhekwe khona lokho bayakwazi ukwenza izinto ezihlehlisayo, omunye angaba kwesokunxele omunye abe kwesokudla, baze balale ngokuhlehla. Ukuziphatha kwabo kuye kwahlolisiswa, lapho umuntu ebonisa khona enye ihlanekezela i-psychology kwenye.
Ezikhathini eziningi lolu hlobo lwamawele lutholwa ngabazali ngokwabo ababona ezinye zezici esezichaziwe. Kufanele kuqashelwe ukuthi Lezi zinhlobo zokukhulelwa ziyivelakancane kakhulu, kodwa akunakwenzeka. Kulokhu, ngokuqinisekile uyazi ngecala.
