I-Gemini i-fraternal kunye ne-odnoyaytsevye: ukungafani

Ukuzalwa komntwana kuyinto engavamile, inomdla. Ubomi bonke bomama osemncinane buqala ukujikeleza ummangaliso omncinci ofikile kwihlabathi. Kwaye ukuba inkazana inikwe abancinci ababini (okanye ngaphezulu), ngoko lonwabo luba lukhulu.

Ukuzalwa kwamamawele kuthwala umonakalo, ozayo uyakhathalela unyameko, ubusuku bokulala, nangona kunjalo ixesha lokuzalwa kwabantwana lizaliswa luvuyo.

Uhlobo lweamawele

Ukuba ibhinqa inokukhulelwa okubanzi, iya kuba namawele. Abantwana banokubambisana ngokufanayo, kwaye ngokuqhelekileyo bafana okufanayo, kwanokuba baxhatshazwe. Konke oku kuxho mekeke kwindlela ukutsalwa kweqanda kwenzeka ngayo . Kuxhomekeke kule nto, amawele ahlukaniswe:

• Iqanda elilodwa (monozygotic);
• URaznoyaytsevyh (i-dizygotic).

Mawele

Ukuzalwa kwabantwana ababini ngokufanayo kuya kuhlala kuyimfihlelo yoluntu. Kutheni kwinqanaba lokuqala liqala ukwabelana ngeqanda kwaye lenze ama-embryos ofanayo, ahlale engaziwa.

Amawele e-Monozygotic yiphumo lokuchumisa iqanda elinye kunye nesidoda esisodwa. Isisombululo se-diploid esiphumela siqala ukwahlula, okubangele ukubunjwa kweembrusi ezizimeleyo. Ngokuqhelekileyo kukho ezimbini, kodwa kunokubakho ngaphezulu. Ubungqina beintsana ezizayo ezivela kulolu khulelwe lunqunywe ngethuba lokuhlukana kwemibungu. Ukuba kwenzeka ezinsukwini ezi-5 zokuqala, imibusi nganye ine-placenta yayo kunye ne-amniotic fluid. Kule meko, kuya kuba neentlukwano ezincinci ekubonakaleni kweintsana ezizayo. Ukuba isahlulo sifikile emva komhla wesihlanu, ii-embrasi zinendawo enye efanayo kunye nokufana kwazo kuya kuba nzima.

Inyaniso enomdla: amawele e-monozygotic amaninzi afana neminwe efanayo.

Izizathu zokwahlula i-zygote zibe ngama-embrasi amabini okanye ngaphezulu awanakucingwa. Ubunokwenzeka bokuzalwa kwabantwana abafana no-3 ukuya ku-1000 kwaye aluxhomekeke kubuhedeni.

Amamawele angenangqondo

Ukukhulelwa kwala mawele afunyanwa ngenxa yokuchumisa i-ovules ezimbini nge-spermatozoa ehlukeneyo. Ngentuthuko ye-intrauterine, nganye imbungu ine-placenta yayo kwaye ikhula ngokuzimeleyo kwenye. Amawele e-Dizygotic angaba ngumntu ongatshatanga okanye ulwabelana ngesondo. Baya kuba nokufana okufanayo, njengabazalwana kunye noodade abavela kwi-single-single-pregnancy.

Amamawele angenangqondo Ukufunyanwa kungabakho umehluko weeyure eziliqela, mhlawumbi neentsuku ezimbalwa.

Izixhobo zokuphuhliswa kwamawele angama-dizygotic

Ziyaziwa ngeenyaniso ezinjalo malunga namawele ahlukeneyo:

• Izahlulo zabo zihambelana nama-40-50%;
• I-embryo nganye ine-placenta yayo kunye ne-amniotic fluid yayo;
• Iintsana ezizalwayo zinokuthi zingatshatanga okanye zingabambiselani;
• Abantwana banokuba neentlobo zegazi ezahlukeneyo;
• Ubungakanani bokuba kwenzeka kwabo banda kumabafazi abangaphezu kweminyaka engama-35 ubudala;
• Ngenxa yeenkqubo ze-IVF, amawele avela kaninzi, njengoko amaqanda amaninzi azaliswayo atyalwe ngumfazi.

Ngaba ngokwenene ukuceba ukuzalwa kwamawele?

Ukuzalwa komntwana kuyinto engavamile, enomdla eyenzeka kumama oselula ozalela umntwana. Kwaye ukuzala kwamawele (amawele) kunokuba luncedo ngakumbi kwintlalo yolonwabo. Nangona kunjalo, akunakwenzeka ukucwangcisa ukubonakala kwazo.

Xa i-ovum ixiliswa, ulwazi lukhawuleza lubekwe kwintsana elizayo kwaye luhlobo luni lokukhulelwa oluya kubakho - ukuxhumela okanye ubuninzi, ngoko akunakwenzeka ukuthonya le nkqubo ngokwemvelo. Omnye unokufumana kuphela izinto, ukuba ziyabonwa, ithuba lokubonakala kwamawele liyakhula.

Ezi zinto ziquka:

• Ukukhulelwa kwi-35-39 iminyaka;
• Ukuba khona kwamawele kwisizukulwana (ukubonakala kweeqanda ezifanayo akuhambelananga nezinto ezinobuncwane.) Kuze kube namhlanje, akuzange ifundwe ukuba kutheni kwaye phantsi kweyiphi imeko i-oocyte iqala ukwahlula);
• Umjikelezo omfutshane wokuya esikhathini (iintsuku ezingama-20-21) - kunye nalo mjikelezo unako ukukhula komama amaqanda amaninzi;
• Unyango lokungabikho. Kwonyango lokusetyenziswa kweziyobisi ze-hormonal usetyenziso olukhuthaza ukuvuthwa kwe-ovum kunye ne-ovulation, umphumo unokuba nokukhulelwa okubanzi;
• Ukugqithiswa kokufakelwa komzimba - okwezinye izinto, kubakhokelela ekuzalweni kwamawele okanye iintsana ezingaphezulu.

Ukwahlukana phakathi kwamawele kunye namawele

Kunokwenzeka ukuqokelela ngokubhekiselele kwinto ekwahlula amawele afanayo ukusuka ku-raznoyaytsevyh. Makhe siqwalasele iimpawu eziza kuba nezingane ezizalwe ngokukhulelwa okubanzi.

Amawele athile:

• Abantwana banokufana okufanayo, kodwa ngezinye iimeko kunokubonakala. Umzekelo, umfanekiso wesirangqangi wee- moles ezikhoyo.
• Ngaphandle kokufaniswa kwangaphandle, umzimba, isakhiwo seenwele, ilungiselelo lamazinyo, isiqalo sezwi, kunye neengcamango zifana noko.
• Bafumana uhlobo olufanayo lwegazi kunye neenkcukacha ezininzi zeminwe efanayo.
• Zisoloko zifana ngesini-nye, zibizwa ngokuba ngama-clones.
• Akunakwenzeka ukucwangcisa ukuzalwa kwamawele e-monozygotic.

Amabhinqa angama raznoyaytsevye:

• Kukho bobulili obufanayo kunye nesondo esahlukileyo.
• Unokuba namaqela ahlukeneyo egazi.
• Ukungafani kwangaphandle kungaphezulu.

Kubonakala ukuba akukho zifana phakathi kwamawele afanayo kunye ahlukileyo, igama elinye kuphela "amawele". Ngexesha elifanayo, kungokwesiko ukuba abantu babize amawele amawele afanayo, kunye ne-raznoyaytsevyh - amawele, ama-triplets, njl. Ukungafani phakathi kwabo kuyaqala ukubonakalisa ukususela ngexesha lokukhulelwa.

Isiphelo

Ukuvela kwamantombazana amabini okanye ngaphezulu ngenxa yokukhulelwa okunye kuthatha ingqwalasela eyongeziweyo yabantwana abajikelezile kubantwana. Kule meko, amawele afanayo afana nabazalwana kunye noodade abaqhelekileyo (2 odade okanye abazalwana aba-2), ngoko abanakuchukumisa.

Amawele afanayo afanayo athatha umdla kubantu. Oku kunokwenzeka ukuba, oku kungenxa yokunqongophala kwesi siqalo. Ngoko ke, kubona abantu ababini bafana nabo, umntu odlulayo uya kubabeka amehlo abo.

Ngelo xesha, kubalulekile ukwazi ukuba ukukhulelwa okubanzi kubonwa phantsi kolawulo olukhethekileyo, kuba umzimba ufumana umthwalo omkhulu kunokuba ngexesha lokukhulelwa okuqhelekileyo. Umama ozayo kufuneka alumkele impilo yakhe. Ngoko ke, ukuze kuzalwe amawele aphilileyo, kuyimfuneko ukuphulaphula iziphakamiso zogqirha, ngoko umzuzu wokudibana kunye nezingane uza kuzaliswa kuphela.
