Iintlobo ezingavamile kunye ezingaqhelekanga zamawele

Uninzi lwabazali baqhelanise neentlobo ezimbini zeewele-zentlalo (i- dizygotic ) kwaye zifana ( monozygotic ). Ngaphandle kwezo zigaba eziphambili, zikhona ezinye iintlobo ezingabonakaliyo kunye nentsholongwane yokwahlula. Ezi ntlobo eziqhelekileyo nezingavamile zeewele azivumelekanga ukuba zihlangane nazo.

Amabini Amabini

Amawele adibeneyo aphindaphindiweyo ngokungafani ngokupheleleyo nomnye ngenxa yokuhlukana ngokupheleleyo kwe-ovum. Abantu ngabanye baya kuxhunyezwa kumanqaku athile omzimba kwaye banokwabelana ngesisu, izitho, okanye izitho.

Amawele ayenziwe ngokwahlukileyo: Ukugqithisa

Ngokuqhelekileyo xa iqanda litsalwa, umjikelo wesifazane uphazamisekile kwaye ukuphelisa i-ovulation kuyaphela. Ngokuqhelekileyo, kunjalo, iqanda liyakhululwa xa umfazi sele ekhulelwe. Oku kubangela amawele awakhulelwe ngamaxesha ahlukeneyo, eyaziwa ngokuba yi- superfetation .

Amabhinqa aBawo ahlukeneyo: I-Heteropateral Superfecundation

Abazalwana (ama-dizygotic) amawele aphumela ekuhlaleni, ukukhululwa kwamaqanda amaninzi kumjikelezo omnye. I-Superfecundation ichaza imeko apho amaqanda ahlonyelwa khona ngesidoda esivela kwiziganeko ezihlukeneyo zesondo.

Kwimeko apho ibhinqa ilala neentsebenziswano ezahlukeneyo, amawele angaba noobahlukeneyo. Ixesha elifanelekileyo le yinto yokuqulunqwa kwesibindi .

"Isiqingatha esingaqhelekanga" Amabhinqa: Amathumbu amaQela ePolar

Iintlobo ze-Dizygotic (izizalwana) zibangelwa xa amaqanda amabini ehlonywa. Iimbono zeMonozygotic (ezifanayo) zivela kwiqanda elilodwa elinomhlaza oluqhekezayo. Kodwa kuthekani ukuba iqanda lihlukana kwaye isiqingatha ngasinye sidibana nesidoda?

Leyo yintetho ephakanyisiweyo ye-polar body okanye "amawele afanayo" afanayo, amawele afana kakhulu kodwa ayingekho i-100 yepesenti yeDNA. Nangona kubonakala ngathi yingcamango ecacileyo, akukho vavanyo olucacileyo lokuqinisekisa ukuba i- polar body twinning .

Umfana / Intombazana eqhelekileyo (i-Monozygotic) Amawele

Ngokufanayo (i-monozygotic) amawele ahlala efana nesini. Oku kubangelwa ukuba bafake kwi-zygote enye equlethe i-chromosome yesini (i-XY) okanye i-female (XX).

Nangona kunjalo, kukho iimeko ezimbalwa ezixeliweyo zokuguquka komzimba kwiimpama zamadoda apho elinye iwele lilahlekelwa yi-Y chromosome kwaye likhula njengowesifazane . Iwele lesibhinqa liza kuba ne-Turner's syndrome, ebonakala ngokukhawuleza kunye nokuntuleka kophuhliso lwe-ovari.

Iimbilini zeMirror-Image

Amawele e- Mirror-image ayenama-monozygotic-amawele afom oluvela kwiqanda elilodwa elinomhlaza. Xa ukwahlukana kwenzeka emva kwexesha elide emva kweveki emva kokukhulelwa-amawele angahlakulela iimpawu ezingenakulinganiswa.

Eli gama alilona uhlobo lwamawele, nje indlela yokuchaza iimpawu zabo zomzimba. Ngokomzekelo, banokuthi bangakwesokudla nangokunxele , baneempawu zokuzala kumacala athile emzimbeni wabo, okanye babe neenwele zeenwele ezihamba ngeendlela ezichaseneyo. Kwimfundiso, ukuba amawele ahlangane, aya kubonakala ebonakaliswa ngokukodwa komnye nomnye. Amaphesenti angama-25 eamawele afanayo ayenamawele angama-mirror.

Amacangqa amaPasasitic

Amawele e-parasitic abhekisela kwimihla yamawele ahlangeneyo aphuhliswa ngokungenasemgangathweni, kunye neincinci ezincinci, ezingaphantsi kwama-twin ezixhomekeke kunamandla, amawele amakhulu. Omnye umzekelo opapashwe kakuhle nguManar Maged oye wafumana ingqalelo emva kokubonakala kwi-Oprah.

Ukwahluka kwe-twinning ye-parasitic yi "fetus fetus," apho inqwaba yeeseli ikhula ngokungaqhelekanga ngaphakathi kwidumbu le-twine le-monozygotic. Kuphila ngexesha lokukhulelwa, kwaye nakubakho emva kokuzalwa, ngokuthe ngqo ngqo kwigalelo legazi lomntu wesibini. Kungenzeka kutholakale nakumntu omdala.

Amacangwana angama-Semi

Amawele athile angafaniyo uluhlobo lovuko oluchongiweyo kwiibini zemawele aneminyaka emithathu ngo-2007. Ukuchazwa njengento efanayo kumacala kamama kodwa ukwabelana ngesigamu seengcambu zooyise, amawele angamaqabunga aphuhliswe xa iimbumba ezimbini zizalisa iqanda elilodwa, ekwahlukana. Elinye iwele i-hermaphrodite iphakanyiswa njengowesifazana, kunye nezakhiwo zombini kunye ne-ovarian, ngelixa enye enye i-anatomically male.

Amawele Amabhinqa ahlukeneyo

Ingcaciso eqhelekileyo yeewele ngeentsuku ezahlukeneyo zokuzalwa ngumsebenzi kunye nokuhanjiswa okuqala phambi kobusuku ngenye imini kwaye iphelile emva kokutshintsha iwashi ukuya kusasa. Ukuba loo mini iyenzeka ekupheleni kwenyanga, okanye nangomhla woNyaka kaNtshonalanga / Usuku, ezi ziintsana zinokuzalwa ezinyangeni ezahlukeneyo kunye neminyaka eyahlukileyo.

Kwakhona, ngamanye amaxesha ukukhulelwa kuthatha ixesha elide ukunika umntwana ngamnye ithuba lokuphila. Ukuba imisebenzi yamabhinqa yokuqala ukuhanjiswa komntwana omnye, oogqirha bangakwazi ukulawula ngempumelelo umsebenzi kunye nokulibaziseka kwezibonelelo ukunika elinye ixesha ixesha elithile kwisibeleko. Amawele kunye nokuphindaphinda okuphezulu azalwe iintsuku kunye neeveki ezihlukeneyo.

Amawele eentlobo ezahlukeneyo

Ukufundwa kwezilwanyana zezilwanyana kungachaza iziganeko zeentlobo zobuzalwana (i-dizygotic) ngamafa kunye neemeko zobuhlanga ezahlukeneyo. Kwesinye isihlandlo, ukwahlukana kwakungenxa yokuxubusha kweebhodi ngexesha le-in vitro inkqubo.

Nangona kunjalo, ngo-2005 e-United Kingdom, abazali ababini bezobuhlanga babetha amantombazana amancinane (i-dizygotic) amantombazana, i-Kian noRemee Hodgson. Ichazwa ngokuthi "enye kwisigidi" kwenzeka, iingcali zichaza ukuba amantombazana azuze iimpawu ezahlukahlukeneyo zofuzo ezivela kubazali bazo. Omnye unobunono obunobunono obunobumba obukhanyayo ngelixa elinye linamakhanda omnyama, amehlo kunye nesikhumba.
