Ukugqithiseleyo kakhulu kodwa kunokwenzeka ngakumbi ngeNkqubo zoNzala eziNcedisayo
Izilwanyana ezintathu zithwele kwisibeleko ngexesha lokukhulelwa okukodwa. Njengamawele, ama-triple kunye nezinye iziphindaphindiweyo ze-multiples zingafakwa ngokwezigaba zabo. Nangona abantu abaninzi beqhelana nemigca "efana" kunye "nabazalwana" ekuchazeni iziphindaphindiweyo, kwaye sebenzisa le migaqo ukucacisa ukuba amawele okanye amathandathu akhangeleka, afana neyona nto ibhekisela kuyo ukuba iifestile ifom.
Uninzi lweentathu zintathu zi-trizygotic, ezithetha ukuba umntu ngamnye uvela kwi-zygote ehlukile, okanye inhlanganisela yeqanda / i-sperm. Ngokuqhelekileyo zichazwa njenge "ezininzi" kwaye zikwabelana ngokufana kohlobo lwezofuzo ezifana nabantakwabo. Nangona kunjalo, akuqhelekanga ukuba ezintathu zibe zi- dizygotic , ezenzeka xa amaqanda amabini ehlanjululwa ngedoda, kwaye enye yeqanda ekhulile iyahlula zibe zibini. Okubalulekileyo, ezimbini zintathu zifana namawele e-monozygotic (afanayo), ukwabelana ngeempawu ezifanayo zeDNA, ngelixa iqela lesithathu liveliswe ngenye inhlanganisela yeqanda / yesininzi kwaye inokwenziwa kobugcisa obuhlukile kwezinye iimbini ezimbini.
Iimbono zeMonozygotic
Akunqabile ukuba ezintathu zibe monozygotic ngokupheleleyo, nto leyo ithetha ukuba bonke abantwana abathathu bavela kwiqanda elilodwa elihlukanisa iindlela ezintathu okanye lihlula zibe zimbini kwaye enye yezo zibini zahlukana kwakhona, ekugqibeleni zibangele imibusi emithathu eneempawu ezifanayo zeDNA.
Iimbono ze-Monozygotic zihlala zifana ngesini, nokuba ngabafana bonke okanye bonke abantombazana. Ezinye i-monozygotic triplets empeleni ziyi-quadruplets apho enye imbungu ilahlekile okanye ibuyiselwe kwakhona.
Ukukhulelwa kwe- tripletti ye-monozygotic inomngcipheko wokukhulelwa kwe-monozygotic kunye ne-placenta ebelwanayo, kunye nemingcipheko eyongezelelweyo yokukhulelwa kwe-triplet.
Ukukhulelwa kolu hlobo kunokwenzeka ukuba kuhlangane neengxaki ezinjenge- pre-eclampsia , abasebenzi bokuqala , kunye ne-transfusion syndrome.
Ngenxa yokungalindelekanga, ama-triplets afanayo aqhele ukwenza i-headlines, umzekelo xa ukukhulelwa kwe-triplet triplet kudala emva kokuba umbindi omnye uqaliswe kwinkqubo ye-vitro. U-Allison Penn wazala u-Logan, uEli, kunye noCollin ngo-Matshi 2008. Oogqirha bakhe bachonga le meko nje ngokuba yimeko eyaziwayo yodluliselo olulodwa lwesibindi elibangelwa ukutshatyalaliswa kwesibindi.
Ziziphi iziganeko?
Uphando luhluka kwiimeko zeemonozygotic kathathu. Ingxelo yecala lika-2012 yesicwangciso esilungileyo seentathu ezifana nabafana abathathu abathandwayo bahlawula ngokukhawuleza iziganeko ezi-1 kwii-100 000 ezizalweni zokuzalwa, kunye nezona ziganeko ezichazwe ngamacandelo okuzala okuncedisayo. Leli phepha laphawula ukuba kukho ezinye iimeko ezisixhenxe kuphela ezaziyaziwayo. Uxwebhu luka-2015 lubhala izinga leemeko zezihlandlo ezifanayo ngokuphindaphindiweyo ngama-100 ngokuphindaphindiweyo kunye neendlela zokuncedisa ukukhulelwa ngaphandle kokukhulelwa kwangaphandle kodwa kusenqabile kakhulu.
Okwangoku, uqikelelo olubonwayo kwiimidiya ezithandwayo zivela phakathi kwe-1 kwi-60,000 kunye ne-1 kwi-200 yezigidi. Oku kunokwenzeka ngenxa yamanani athile abonisa izinga lembono / ukukhulelwa kunokuba bazalwe ngokuzalwa kwama-triplet.
