Inkwenkwe nentombazana yaseGemini

Ngaba amawele asebukhosini athetha ntoni - imfihlelo yendalo, okanye isipho sengozi kubazali abakhethiweyo? Ngaba ingaba luvavanyo olunzulu? Kakade, ezimbini ezifanayo zangaphandle, kodwa ngexesha elifanayo ngesondo esisodwa - intombi nomntwana omncinci - lo lonwabo lonene. Kodwa ngexesha elifanayo - uxanduva olukhulu, kwaye xa ungeze ingozi yokuhlukana kwemfuza eyahlukeneyo, kuya kuba kuhle ukuba abo babini bahlangane omnye kwiwaka.

Ngokwezibalo, abantwana ababini yinkwenkwe nentombazana-into eqaqambileyo ukuba emva kokufunda malunga nokukhulelwa okuphindaphindiweyo, amaninzi omama kunye noodade, kunye noogqirha, kwaye ungacingi ukuba amawele asebukhosini angazalwa. Emva koko, iintsana ezingenabantwana, ngokuqhelekileyo zibangelwa ukuchumisa amaqanda amabini, ngamawele, kodwa kungekhona amawele. Nangona kunjalo, amabali ayaziwa ngamacala xa kwakunjalo ukukhanya okwakubonakala umzalwana noodade, befana njengamaconsi amabini amanzi.

Ngaba ngaba amawele, okanye onke amawele afanayo, intombazana kunye nentombazana ezalwe ngohlobo oluthile olufanayo? Masizame ukuyifumanisa.

Ngaba inkwenkwe nentombazana enjalo ingaba ngamawele?

Akunakwenzeka ukukhanyela loo nto, kwaye ukukhanya okukhawuleza kuye kwachithwa yi-sayensi yokuzalwa okungaqondakaliyo amawele ahlukeneyo ngokwesondo. Ewe, kunokuba, nangona kunqabile kakhulu.

Sonke siyazi ukusuka kwizifundo ze-anatomy ukuba amawele avela kwi-zygote enye kwaye abe ne-chromosome efanayo. Kodwa kukho iinkalo ezininzi kunye neenkqubo ezingaqondakaliyo apho amawele avela khona: inkwenkwe nentombazana. Makhe siqwalasele xa kunokwenzeka:

1. Ukuba elinye lamamawele amakhwenkwe "lahleka" i-Y chromosome. Le ngxaki ibhekisela kwinani leempazamo kwaye ibizwa ngokuba yi-Turner syndrome.
2. Xa omnye umntwana ene-X-chromosome enye (i-Clinfelter's syndrome).
3. Kwimeko xa iqanda linalo ixesha lokwabelana phambi kokuchumisa. Kwiimeko ezinjalo, ukuchumisa kwenzeka nge-spermatozoa eyahlukeneyo, kwaye mhlawumbi amawele aya kuba ngabesini ezahlukeneyo.
4. Ukuba iqanda (iqanda ngokwalo kunye nomzimba wayo we-polar) lixutywe ngamaseli amabini. Kwiimeko ezinjalo, iintsana zizalwe ziphilile, zingenayo i-anomalies.

Indlela yokukhulelwa amawele eenkwenkwe nentombazana?

Inkqubo yokwakhiwa kwamawele e-heterozygous ama-monozygotic kunzima kakhulu kwaye ayizange ifundwe ngokupheleleyo. Ngoko ke, njengokungathi ngaba abazali abazange bafune ukuzala amawele amakhwenkwe kunye nentombazana, akunakwenzeka ukuba akunakwenzeka ukuqikelela okanye ukuthintela le nkqubo ngaphambili. Nangona inzululwazi ayimelanga, kwaye kunye ne-introductory enkulu ye-IVF, i-moms ezayo kunye nabagadi banethemba kwixesha elizayo ukulandelelanisa ubulili bezingane kunye nolwazi lwabo.
