Isenzeko esingaqhelekanga se amawele ezibuko Kuyinyani ukuba yenzeka kunqabile kakhulu phakathi kwe-25% yamatyala. Igama elithi "isipili" lisetyenziselwa ukuba abantwana abazalwayo bafane ngokupheleleyo, njengamaconsi amabini amanzi.
Ngabantwana abazalwa benjalo amawele afanayo, oko kukuthi, zidalwe ngaphakathi kwesibeleko ngenxa yokukhulelwa kweqanda kunye nesidoda esinye. Zenza i-zygote ize yona yohlulwe ibe ziimbumba ezimbini. Ngeenkcukacha ezithe vetshe siza kuhlalutya ukuba zeziphi iimpawu ezingakumbi abanazo.
Zinjani iicufflinks zesipili?
Njengoko sele sichazile, ngamawele afanayo. Bafana okanye bangamawele e-monzygotic. Zinezinto ezikhethekileyo, ukuba zidalwe ngenxa yokuqhama kweqanda nedlozi, kwaye ngokulandelayo, yenza i-zygote kwaye yohlulwe kwiimbumba ezimbini. Ngexesha elifanayo banolunye uphawu olukhulu, la mawele aphuhla kwaye babelana nge-placenta efanayo kunye ne-amniotic sac.
Kutheni bohlukile kwabanye abakhulelweyo abangamawele?
Ukukhulelwa kwamawele kunokwahlulwa ukusuka kwelinye ukuya kwelinye ngexesha i-zygote idala isahlulo sayo. Kukho iimeko ezahlukeneyo:
Amawele angafaniyo okanye e-dizygotic
Babizwa ngokuba ngamawele. Sisiphumo seembumba ezimbini ngaphakathi esiswini, kodwa kulo mzekelo umfazi uyakhupha ii-ovules ezimbini kwaye zombini zikhuliswa ngamadlozi amabini ahlukeneyo. Kule meko sithetha ngabantwana ababini abaye bakhula kwisibeleko esifanayo kwaye abazange babelane nge-amniotic sac, okanye i-placenta, kwaye abanalo ufuzo olufanayo. Ababini kwabathathu abakhulelweyo abaninzi bolu hlobo.
Amawele afanayo okanye e-monozygotic
Ngabo sele bechaziwe. Oku kuxa iqanda liye laqhama kwaye apho i-zygote ihlukana kubini. Xa kusahlulwe, iimbumba ezimbini zidalwe zinomthwalo ofanayo wemfuza.
- I-Bichorial kunye ne-diamniotic. I-zygote yahlula-hlula kwiintsuku ezintathu emva kokukhulelwa. Kule meko, iimbumba ezenziweyo zondliwa yi-placenta yazo kwaye zikhule kwi-amniotic sac yazo.
- I-Monochorionic kunye ne-monoamniotic. Ukwahlulwa kwe-zygote kwenziwa emva kwexesha elide, phakathi komhla wesixhenxe kunye neshumi elinesithathu lokuchumisa. Apha ama-embryo abelana nge-placenta efanayo kunye ne-amniotic sac efanayo. Yilapho amawele esibuko anokuthi aqulunqwe khona, nangona adala uphawu lokwahlula phakathi komhla wesithoba kunye neshumi elinesibini emva kokuchumisa. Kule meko, ulwahlulo lwe iiseli ezifanayo kanye, enye ngasekhohlo kwaye enye ekunene.
Ngeli xesha kunokuba yimeko iwele elinyamalalayo, apho elinye imbumba lingagqibi ukukhula lize lifunxwe ngumama, yiplacenta okanye ngomnye umzalwana. Eli tyala liyaziwa xa i-ultrasound yesiqhelo yenziwe kwinyanga yesithandathu yokukhulelwa kwaye kuye kwaphawulwa ukuba kukho iimbumba ezimbini okanye ngaphezulu. Kamva, kwenye i-ultrasound elandelayo, enye yazo iyanyamalala kwaye enye iyaqhubeka ikhula ngaphandle kwengxaki.
Iimpawu ezikhethekileyo ze-mirror cufflinks
Aba bantwana bajongwa ngeempawu zabo ezikhethekileyo xa bezalwa. Amalungu aphuhlileyo emizimbeni yawo anokudalwa ngendlela eyahlukileyo. Zombini intliziyo, isibindi kunye nodaka zibekwe ukusuka kwelinye ukuya kwelinye kumacala ahlukeneyo emizimbeni yazo. ngumnxeba "situs inversus" kwaye yenzeka ngokunqabileyo kakhulu, kuphela imeko enye kwi-10.000. Nokuba isiphumo sesibuko sinokudalwa kunye neempawu ezingabalulekanga kakhulu njengeenwele, iimpawu zokuzalwa okanye iimoles.
Idatha nayo icacisiwe apho ibonwe ukuba bayakwazi ukwenza izinto ezibuyisela umva, omnye unokuba linxele kwaye elinye libe linene, bade balale ngomva. Ukuziphatha kwabo kuye kwafundwa, apho umntu ubonakalisa enye ireverse psychology ukuya kwenye.
Kwiimeko ezininzi olu hlobo lwamawele lufunyaniswa ngabazali ngokwabo abaqwalasela ezinye zeempawu esele zichaziwe. Kufuneka kuqatshelwe ukuba Ezi ntlobo zokukhulelwa zinqabile kakhulu, kodwa azinakwenzeka. Kule meko, ngokuqinisekileyo uyazi ngemeko.
