Amawele amabini akhula xa amaqanda amabini edibene namadlozi amabini ahlukeneyo. La maqanda mabini aqhanyiweyo afaka esibelekweni aze akhule. Ngokungafaniyo namawele afanayo okanye e-monozygotic, ababelana nge-100% ye-DNA yabo, amawele azalwana abelana kuphela malunga ne-50% ye-DNA yabo. Ngesi sizathu, abafani ngokwemfuza kunabo bonke abantakwabo, ukuba banayo.
Amawele namawele angoowethu aye asoloko engumxholo weentsomi neemfihlelo, kwakunye nokuba ngumthombo womdla kwabaninzi. Ekubeni isiphumo sokukhulelwa okufanayo, kukho izinto ezinomdla abangazibelaniyo nabanye abantakwabo. Ukuba uyazi naziphi na iimeko zamawele kwaye unemibuzo malunga nezi ntsomi, qhubeka ufunda kuba siza kubona ezinye zezona zinto zimangalisayo zamawele.
Zeziphi ezona zinto zimangalisayo ezinomdla kumawele?
Ziyeyona ntlobo ixhaphakileyo yokuzalwa kwabantu abaninzi
Abantu bawufake ngaphakathi ngakumbi umxholo othi "amawele", ukuqonda kunye nabazalwana abangamawele afanayo. Kuphawuleka ngakumbi ukubona abantu ababini abafanayo kunabazalwana abakwiminyaka efanayo abangafaniyo kangako. Kodwa eneneni, amawele afanayo ayinto enqabileyo yendalo, ngelixa Ukukhulelwa kwamawele kwenza i-75% yokukhulelwa kwabantu abaninzi kwihlabathi.
Ulwakhiwo lwemfuza yabo yahlukile
Njengoko besesitshilo ngaphambili, amawele avela xa amadlozi amabini eqhamisa ii-ovules ezimbini ezahlukeneyo. Ngenxa yokuba zi-ovules ezimbini ezahlukeneyo xa zidibene kwaye zifakwe kwisibeleko, ukukhula kwazo kuzimeleyo. Oko kukuthi, I-ovum yewele ngalinye ivelisa ingxowa yayo ye-amniotic, i-placenta, kunye nezinye izakhiwo zenkxaso ezahlukeneyo.
Banokuba ngabesini esifanayo ... okanye hayi
Njengakuko nakuphi na ukukhawulwa, iichromosomes zedlozi likabawo zimisela isini somntwana ozayo. Ekubeni amawele amabini ephuma kumadlozi amabini awahlukeneyo, qanda ngalinye kula mabini aqhanyiweyo linokuba yinkwenkwe nentombazana, okanye omabini amakhwenkwe okanye omabini amantombazana. Oko kukuthi, amawele anokuzalwa nayiphi na indibaniselwano yesini enokwenzeka: inkwenkwe nentombazana, abafana ababini okanye amantombazana amabini. Kakade ke, sithetha ngokwembono yemfuza. Ukwabelana ngesondo kumiselwa kwisibeleko, ngelixa isini sisakhiwo sentlalo kunye nento umntu azenzele isigqibo ngayo kamva.
Amawele anokuba nootata ababini abahlukeneyo.
Le nto iyinyani kwaye ibizwa ngokuba yi-super fertilization okanye amawele amabini. Oku kwenzeka xa ibhinqa likhupha amaqanda amaninzi, aziwa ngokuba yi-hyperovulation. Ukuba le hyperovulation yenzeka kwaye umfazi uye walala ngokungakhuselekanga kunye neqabane elinye, la maqanda anokuqhanyiswa ngamadlozi aphuma kumadoda amabini ahlukeneyo.
Banokuzalwa ngeentsuku ezahlukeneyo
Enyanisweni, banokuzalwa ngeentsuku, iiveki, okanye kwinyanga eyahlukileyo. Masithi ibhinqa likhupha iqanda ebudeni bomjikelezo walo lize liqhame, kodwa umjikelo walo uyayeka. Xa efikelela kumjikelo olandelayo, ngaloo ndlela ekhupha elinye iqanda, sele ekhulelwe, kodwa elo qanda lesibini lisenokuqhama. Oku kunokwenzeka ukuya kwiintsuku ezingama-24 emva kokukhululwa kweqanda lokuqala, okukhokelela ekubeni amawele azalwe kwiiveki nje ezimbalwa elinye kwelinye. Lo mcimbi waziwa ngokuba yi-superfetation.
Zinokwahluka ngokupheleleyo
Akukho mthetho ungabhalwanga othi abantwana abazalwa kwintsapho enye bafanele bafane, nangona abantu besoloko becinga njalo. Kodwa ekubeni amawele abelana kuphela nge-50% ye-DNA yawo, banokuba neempawu ezahlukeneyo kunye nezinto abazikhethayo xa kufikwa kubuntu babo. Ngokungafani namawele afanayo, anobudlelwane obunamandla ngakumbi kuba babelana nge-100% ye-DNA yabo, amawele omzalwana anokuba ngabachasayo be-polar. Le yinto enokwenza ukuba umzali kube nzima, kwaye abaphambanise abazali babo, ukutsho nje kancinci.
Amawele nawo anokuba nzima ukuwahlula
Oku kunokuphazamisa. Ngaphandle kwazo zonke iiyantlukwano zabo, amawele anokufana kakhulu ngokwasemzimbeni. Kwiintsapho ezininzi kukho abantakwabo abafana kakhulu ngenxa yokwabelana ngemfuza, kodwa iminyaka yabo iyahluka kwaye, ngoko ke, akunakwenzeka ukuba badideke. Kwimeko yamawele, ngoobhuti abalingana ngeminyaka kwaye loo nto yenza kube nzima ukuwohlukanisa. Ngenxa yoku, ngamanye amaxesha kunzima ukwahlula amawele angamaqabane kumawele afanayo. Ekuphela kwendlela echanekileyo yokubona umahluko kungovavanyo lwemfuzo lwe-DNA zygosity.
