Xaalad aad u daran laakiin wax badan oo ka mid ah hababka taranka ee taranka
Saddexjibbaarane waa saddex carruur ah oo lagu qaado ilmo-galeenka inta lagu jiro hal uur. Sida mataanaha, saddex-geesoodka iyo dhereraadka kale ee sarreeya ayaa lagu kala saari karaa jimicsigooda . Inkasta oo dad badani ay yaqaanaan ereyada "isku mid" iyo "malaayiin" oo ku tilmaamaya dhajinta, oo isticmaalaan shuruudahan si ay u qeexaan in labka ama saddex dheddig ahi ay u egyihiin mid la mid ah, waxa ay dhab ahaantii tixraacayaan sida uu yahay qaabka dhererka.
Meelaha badankoodu waa saddex-gelyo, taas oo macnaheedu yahay in qof kastaa uu ka soo galo jigsasho gaar ah, ama isku-darka ukumaha / shahwada. Waxaa badanaa lagu qeexaa "dheelitirka" dhufaysyada waxayna wadaagaan isku midka la midka ah ee la midka ah ehelada walaalaha ah. Si kastaba ha noqotee, maaha wax aan caadi aheyn in saddexda dheddig ahi ay noqdaan kuwo isku buuqsan , taasoo dhacda marka laba ukun oo bacrin ah la bacrimiyo, iyo mid ka mid ah ukumaha bacriminta loo kala qeybiyo laba. Asal ahaan, laba ka mid ah saddexda ilbiriqsi waa mataano (isku mid ah) mataano, oo wadaagaya sifooyinka guud ee DNA, halka saddexaadood ay soo saareen ukumo kala duwan / shahwo kala duwan oo leh unugyo hidde ah oo cajiinka ah oo ka soo baxa labada sadexda kale.
Saddexleyda Monozygotic
Waa dhif u ah saddexda ilbiriqsi inay noqdaan gabi ahaanba monozygotic, taas oo macnaheedu yahay in dhammaan saddexda carruurba ay ka sameeyeen ukun kali ah oo kala qaybiyay seddex siyaabood ama kala-gooyey laba ka dibna mid ka mid ah labada qaybood mar labaad, ugu dambeyntii waxay keentay saddex embriyono oo leh astaamaha guud ee DNA.
Saddexda xisaabeed ee monozygotic ayaa had iyo jeer ah jinsi isku mid ah, dhammaan wiilasha ama dhammaan gabdhaha. Qaar ka mid ah saddexda dhuxusha ee loo yaqaan 'monozygotic' ayaa dhab ahaan quadruplets ah halkaasoo hal embraan oo la lumay ama dib loo soo celiyay.
Xaamilada saddex geesoodka ah waxay uur leedahay halista ah uur qaadida joogtada ah ee lala socdo mandheerta la wadaago, oo lagu daro khataraha dheeraadka ah ee uurka uurka.
Uurka udhaca noocan ahi waxay u badan tahay inuu la kulmo dhibaatooyin sida pre-eclampsia , uur -ku- taagga , iyo xitaa xinjir dhiigga ku jira.
Sababtoo ah caanaha, saddexdaas isku mid ah ayaa badanaa sameeya cinwaannada, tusaale ahaan marka uureysiga monoligotic triplet dhaliyey ka dib markii hal embraane lagu geliyey nidaam vitro-ga ah. Allison Penn wuxuu dhashay Logan, Eli, iyo Collin bishii Maarso 2008. Dhaqaatiirteeda ayaa xaalada ku ogaaday xaaladdan keliya ee lagu ogaanayo hal wareeg oo xayeysiin ah taas oo keentay saddex laab.
Maxay yihiin Miisaanka?
Cilmi-baaristu waxay ku kala duwan tahay dhacdooyinka saddexda dhuxusha. Warbixinta kiisaska 2012-ka ee caafimaad leh ee saddexda wiil ee isku-dhafan oo isku mid ah ayaa uuraysta si isdaba-joog ah liiska ugu jira 1 qof 100,000 oo dhalasho nool, iyada oo inta badan kiisaska la soo sheegay ay ubadkoodu ku habboon yihiin farsamooyinka taranka. Qoraalkan ayaa xusay in todoba kale oo kiis oo kale loo yaqaanay in si isdabajoog ah loo uuraysto. Xaashida 2015 waxay muujineysaa heerka joogitaanka saddexda isku mid ah isku midka ah 100 jeer marar badan oo leh farsamooyinka taranka ee caawimaadda marka loo eego rimayga isbeddelka laakiin weli waa mid dhif ah.
Dhanka kale, qiyaasaha lagu arkay muuqaalada warbaahinta ee caanka ah laga bilaabo inta u dhaxeysa 1aad 60,000 iyo 1 qof 200 milyan. Tani waxaa laga yaabaa in ay sabab u tahay tirada qaar oo muujinaysa heerka ra'yiga / uurka intaan ku dhalan karin dhalashada ilma-haawenimada.
