Ngaba uke wawava amawele ahlukaniswe njenge-dizygotic okanye i-multizygotic? Kungathi ngathi uhlobo oluthile lwesifo esingaqhelekanga, kodwa i-dizygotic ngokwenene iseshini yesayensi ukuchaza into oyifunayo ngaphambili ... amawele omzalwana . I-Zygosity yindlela yokuchaza indlela amawele afana ngayo.
Ifomu yeDisgogotic Twins Ifomu?
Ifom ye-dizygotic ifomu kumama amaqhekeza ahlukeneyo azaliswe ngamabini amabini ahlukeneyo.
(Di = 2, zygotic = zygote) Kwiimeko ezininzi, ibhinqa likhupha iqanda elilodwa, okanye i-ovum, ukusuka kumanqanda akhe ngexesha lomjikelezo. Kodwa ngamanye amaxesha, ngezizathu ezahlukahlukeneyo, amaqanda amaninzi akhululwa kumjikelezo. Ukuba ukulala ngesondo okanye ukutshatyalaliswa kwenzeke kwaye amaqanda atyunjwa, ukuphindaphinda kungabangela. Amawele e-Dizygotic ayenzeka xa amaqanda amabini ehlanjululwa ngamabini amabini, afakwa kwi-uterus, aze ahlakule amabini. Igama elithi multizygotic lingachaza ezimbini iwele, kunye nezinye iziphindaphindiweyo, ezifana neentathu, ezine-quadruplets, quintuplets okanye ngaphezulu. Ukwahlula ngokuphindaphindiweyo ukuphindaphinda okuvela kwiintlobo ezihlukeneyo, ngokuchasene neziphindaphindiweyo ze- monozygotic ezifomayo kwiqanda eliqeshwayo eliqhekezayo.
Yintoni ebangela amawele eDegogotic?
Ngokungafani namawele e-monozygotic, okungaqondakaliyo, kukho izimbangela ezininzi ze-twinning dizygotic. Ekugqibeleni, zonke ziyakulandelwa emuva kwinto ethile ebangela ukuba umfazi abe ne-hyperovulate, okanye akhulule ngaphezu kweqanda elinye kumjikelezo.
Abanye besetyhini banamathele ukuba benze njalo, mhlawumbi ngenxa yesimo somzimba . Abanye bangenza oko ngenxa yeempembelelo ze-hormonal. Mhlawumbi bancelisa , bathabatha iziyobisi zonyango , okanye baye bayeka ukulawula iipilisi zokulalisa. Abasetyhini abadala banokuthi baxakeke njengokuba imizimba yabo iholele ekupheleni komyeni.
Zininzi ezinye iinkcazo, kuquka ukutya, ubuhlanga, ukukhuluphala kunye nembali yentsapho.
Unokuyichazela njani ukuba iintaba ziyi-Dizygotic?
Unokucinga ukuba unokuthi ukuba amawele ayenayo i-dizygotic ngokusekelwe kwindlela abajonga ngayo. Ngokuqhelekileyo becinga ukuba amawele afanayo (monozygotic) abukeka ngokufanayo ngelixa amawele (dizygotic) amawele ayenzi. Nangona kunjalo, oko akunjalo ngokupheleleyo, njengoko kukho ukungabikho kwimiba yomibini. Ezinye iimbono ze-monozygotic zibukeka zifana ngokufanayo, kodwa ezinye azibuki zifanayo. Ngokufanayo, amanye amawele e-dizygotic anesimo esifanayo, ngelixa abanye bengenzi.
Amawele e-Dizygotic abelana ngokufanayo kwimizimba njengabo nawabanye abantakwabo, njengoko befumana isigamu seDNA yabo kumama kunye nesiqingatha kubabawo. Ngokuqhelekileyo, bangabantu abangama-50 abazalwa ngokusemthethweni. Nje ngezinye iintsapho zibonisa iimpawu eziqhelekileyo zomzimba, amawele angama-dizygotic aya kuba nama-commonalities. Ngaba uke wabuva abantu bethetha, "Uyabonakala nje ngoodadewabo wenza loo nto!"? Iwele ze-Dizygotic zifana neenkwenkwezi ezifanayo; banokuthelekiswa ngecala ngecala elifanelekileyo ngexesha, apho abantakwabo abathandana nabo bafanele bathembele kwiifoto okanye iinkumbulo zemizekelo efanayo.
Kukho iindlela zokumisela ngokuqinisekileyo ukuba ingaba amawele angama-dizygotic.
- Ukuba beyinkwenkwe nentombazana - ZIQEQESHA i- dizygotic (kunye neentlobo ezingaqhelekanga )
- Ukuba baneentlobo zegazi ezahlukeneyo - ZIQINISEKILEYO
- Ukuba kukho i-placenta enye - i- PROBABLY NOT dizygotic
- Ukuba kukho ii-placentas ezimbini - ZINOKUBA zibe yi-dizygotic, kodwa ingaba yi-monozygotic
- Ukuba kukho i-monochorionic - ayiyi-dizygotic
- Ukuba ngaba i- monoamniotic - ayifanelekanga i- dizygotic
- Ukuba zibukeka zifana - ZAKHO zibe zi- dizygotic
- Ukuba uhlalutyo lwe-DNA lubonisa ukungafani kumakishi - BAZIQINISEKILE
- Ukuba uhlalutyo lwe-DNA lubonisa amanqaku ahambelanayo kakhulu - AKAZI- dizygotic
Amawele e-Dizygotic angaba ngamakhwenkwe, amantombazana okanye omnye ngamnye.
Zonke iincwadana / iintombi zamabhinqa zingamawele angama-dizygotic, kunye nezinto ezingavamile kakhulu . Zinqabile ukuba umntu oqhelekileyo akanakwenzeka ukuba ahlangane nabo.
Kungenzeka ukuba kunokwenzeka ukuba ngaba amawele angama-dizygotic ngexesha lokukhulelwa, kodwa ngamanye amaxesha akakwazi ukuqinisekiswa de emva kokuba azalwe. Abantu abaninzi-kuquka abaqeqeshi bezonyango-bacinga ukuba amawele angama-dizygotic ukuba asemagqabini ahlukeneyo kwaye anama-placentas ahlukeneyo, nangona kunjalo, akunjalo ngaso sonke isikhathi. Ngamanye amaxesha, ngokusebenzisa i-ultrasound okanye olunye uvavanyo, izikhombisi zinokukunceda ukufumanisa ubuncwane, ngokwesondo ezahlukeneyo okanye uhlobo oluthile lwegazi. Kodwa ngokuqhelekileyo, ekungabikho kwahlula okunjalo, uvavanyo lwe-DNA yindlela echanekileyo yokuqinisekisa ukuba amawele angama-dizygotic.
