Isigameko se ukuzalwa kwamawele cishe ngo-1 kwabangama-80, okungaphezu kwezingxenye ezimbili kwezintathu amawele e-heterozygous noma e-dizygotic (ahlukene komunye nomunye) kanti amanye angamawele angama-monovular noma ama-monozygotic (afana kwelinye).
Amawele afanayo, okungukuthi I-Uniovular, zivela eqandeni elifanayo elihlanganiswe yisidoda kamuva esizoveza i-zygote eyodwa, okungukuthi, i-nucleus yokuqala ezoba umbungu.
I-dizygotic, ngakolunye uhlangothi, iphuma ekuvundiseni ama-ovules amabili ahlukene, ngayinye ezoba i-zygote enefa elihlukile lofuzo. Umbungu ngamunye uyobe usuba nawo i-placenta yakho kanye ne-amniotic cavity. Ngaphandle kwezinto eziphilayo, akungabazeki ukuthi ukuba namawele kuwumuzwa ongachazeki kumama.
Ilukuluku mayelana namawele:
Nakhu ngikushiya 10 ilukuluku ukuthi mhlawumbe ubungazi...
1 – Amawele anobaba abehlukene
Amawele e-Dizygotic nawo angaba ne-a ubaba ohlukile. Nokho, lokhu kuyivelakancane. Nakuba kungase kube njalo, empeleni kwenzeka kuphela cishe ekuzalweni kwamawele oku-1 kwabangama-400.
2 – Omama bamawele baphila isikhathi eside
Omama bamawele bangaba nempilo ende. Iqiniso nje lokubeletha amawele lingahunyushwa njengohlobo lomvuzo imvelo kamama ukuze ahloniphe eyakhe ikhwalithi yefa lofuzo. Lesi simo sivezwe wucwaningo okukhethekile eyanyatheliswa ngo-2011. Ingabe kumane nje kwaqondana noma kukhona ngempela “okuthile” okubenza baphile isikhathi eside?
3 - Bangaba nesikhumba esinemibala ehlukene
Amawele e-Dizygotic angaba ne-a umbala wesikhumba ohlukile. Lokhu kwenzeka lapho umama nobaba bemunye umbhangqwana oxubile (okuyinto, ngendlela, eyanda kakhulu). Ngamanye amazwi, bekungeke kube yinto engavamile ukuba iwele libe mhlophe kanye nesinye isistimu uma abazali balo bezinhlanga ezihlukene.
4 - "Ulimi olukhethekile"
Amawele aphakathi kweminyaka emi-2 no-4 ngokuvamile akhula a ulimi olukhethekile olubavumela ukuthi baqale ukuxhumana "okukhethekile".. Kuyiqiniso ukuthi noma yimuphi umzalwane angakwazi ukwenza lo mdlalo/isixhumanisi ukuxhumana nabanye futhi abanye abaqondi, kodwa kukhona ukuthambekela okuphawulekayo endabeni yamawele.
Lolu hlobo ikhodi eyimfihlo udalelwe ukushabalala njengoba izelamani zikhula, kodwa ezinye zazo zizoqhubeka nokuzisebenzisa noma sezikhulile. Ngokwemibandela yezobuchwepheshe sikhuluma ngayo » i-cryptophasia «, okuwulimi olwakhiwe izincazelo eziqanjiwe, zezimpawu ezibalulekile nokuthinta komzimba.
5 - Imishado yamawele kanye ne-quaternary
Kubonakale ukuthi uma amawele amabili wesilisa eshada a amawele abesifazane ababili (okwaziwa ngokuthi umshado we-quaternary), izingane zabo zingabhekwa njengezelamani, ngaso sonke isikhathi ngokombono wofuzo.
6 – Ukubhaliswa kokuzalwa
Valentina Vasilyeva, owesifazane waseRussia owazala izingane ezingu-16 wazala izingane ezingu-69, uphethe i- irekhodi isibalo esiphezulu sezingane ezizalwa amawele. Mangisho ukuthi akunzima futhi, ngenani lezingane eyayinazo le ntokazi... Futhi kukhona abakhala ngeyodwa kuphela!
I-7 - I-Gemini: Izigxivizo zeminwe zihlukile
Nakuba bengamawele e-monozygotic, izigxivizo zeminwe zabo zihlukile. Izigxivizo zeminwe zabo, njengoba zifana njengoba zinjalo, azifani. Akuyona nje ikhodi yofuzo, kodwa futhi uchungechunge lwezici ezihlobene nokuthuthukiswa kombungu ku Isibeletho kuthinte izici ze izigxivizo zeminwe. Kufanele ucabange ukuthi ubude obuhlukile benkaba banele ukuze izigxivizo zeminwe zehluke. Into engavamile ukuthi amawele amabili anezigxivizo zeminwe ezifanayo.
I-8 - Amawele ayasebenzisana kakade esibelethweni
Amawele asungula ubuhlobo nomunye nomunye kakade phakathi nokuphila kwe-intrauterine. Emavikini angu-14, isibonelo, bayagona, futhi ngo-18, bayadlala.
9 – EMelika banosuku lwabo olukhulu
I-Twinsburg Itholakala e-United States futhi isendaweni yase-Ohio, lapho amawele egubha khona minyaka yonke ngemibukiso nemicimbi yosuku lwewele. Izifundiswa nabathwebuli bezithombe basebenzisa leli thuba ukuze bathole futhi bangafi izifiso ezintsha mayelana nalaba bazalwane abakhethekile (ikakhulukazi i-monozygotic).
I-10 - Omama abangaphezu kweminyaka engama-35 banamathuba amaningi okuba namawele
Uma owesifazane emdala, maningi amathuba okuthi abelethe amawele. Eqinisweni, abesifazane abangaphezu kweminyaka engama-35 bakhiqiza inani elikhulu le i-hormone evuselelayo ye-follicle (FSH), okuyinto, nokho, inciphisa ngasikhathi sinye ukuzala kwabesifazane.
