Ngaba unamawele awaziwayo? Okanye mhlawumbi unamawele? Yimbonakaliso emangalisayo, kunene? I-Genetics kunye neyeza zibandakanya isifundo sayo rhoqo, kwaye ngexesha elifanayo kusekho into engachangekanga kule ngxaki.
Iinyaniso ezifanayo eziye zityhilwa kwisayensi, siphuthuma ukwabelana nawe.
1. Ukususela ngo-1980, inani lokuzalwa kwamawele liye landa ngo-70%.
2. Abafazi abaneminyaka engama-30 ubudala bazala amawele amaninzi aneminyaka engama-20 ubudala. Ngokuchanekileyo, kamva umfazi ukhulelwe, ephakamileyo amathuba okuzalwa "kwee-casket ezimbili."
3. Isiqingatha esikhulu samawele sizalwe ngesisindo esiphantsi, esinokubangela iingxaki ezahlukeneyo zempilo - njenge-asthma, umzekelo.
4. Oomama abahlala bebekezelela ukubeleka kabini kakuhle. Kwamanye amabhinqa, isifo sengqondo somnxeba sisenza emva koko.
5. Kukhona i-gene ephindwe kabini, kodwa inokuchaphazela kuphela ukuzalwa kwamawele - amawele angamaqabane. Imfuza, eyayiza kuba nexanduva lokuzalwa kwabantwana ababini ngokufanayo - amawele afanayo - akakho.
6. Izindlela ezinjenge-vitro fertilization, vumela ukuzalwa kwamawele ngokwahlukileyo kwiminyaka. Ingundoqo yendlela ikhupha imibusi.
7. Amaduna angaba noobahlukeneyo. Oku kwenzeka ngenxa yesigxina se-heteroterminal - into eyenziwa ngama-ovules amabini omfazi omnye athathwe ngamadoda ahlukeneyo.
8. Kodwa ke, iimbini zeamawele ezivela koobawo ezahlukeneyo aziqabile. I-Sperm kumzimba wesetyhini uhlala usebenze iintsuku eziliqela, ngelixa i-ovum ihlala isebenza ngokungekho ngaphezu kweeyure ezingama-48. Okokuthi, ubude bexesha elivundileyo lifutshane kakhulu.
9. I-vitro fertilization inezinto ezithile ezingenakwenzeka. Ngokomzekelo, omnye umbhangqwana waseDatshi, wamangaliswa gqitha xa efunda ukuba enye yomntwana wayo imhlophe kwaye enye ingumnyama. Kwaye kwenzeka, kuyo yonke into, ngenxa yokuba uMnu. Stewart wesilisa waphambuka ngokugqithisileyo kunye nempahla yomnye umntu ...
10. I-Cryptophasia ngolwimi olukhethekileyo lweewele, eziza nazo njengomntwana. Akukho mntu kodwa yena uyamqonda. Ngokuqhelekileyo iqukethe isandi sezandi ezingenakunyakalala kunye nempawu, kuba umntu ongaphandle, mhlawumbi, uya kumthabatha.
Izifundo zibonise ukuba ubudlelwane obuphakathi kwamawele bubekwe ekuqaleni kweveki ye-14 yokukhulelwa.
12. Kukholelwa ukuba ukuzalwa kwamawele kungafaka isandla kwisondlo esikhethekileyo. Njengoko uqeqesho lubonisa, amawele azalwa ngokuphindwe kabili phakathi "abangewona amaRussia". Abanye oogqirha bakholelwa ukuba ukusetyenziswa kweemveliso zobisi kufumaneka ukubonakala kwamawele.
13. Ubunokwenzeka bokuzalwa kwamawele kumfazi otyelwayo ngexesha lokukhulelwa lixesha eli-9 phezulu kunelo eliqhelekileyo lonina.
14. Candida Godoy, eBrazil, liyinkunzi yelizwe lamawele. Ababini bazalwa apha ngo-8% wokukhulelwa konke. Iingcali zenzululwazi zikholelwa ukuba i-gene "iwele" ekhethekileyo yiswe apha ngabafuduki. Yaye wayithatha ingcambu ngokuqinileyo, njengoko ubona.
15. Ngo-2010, iBanga eliPhakamileyo leB Baker e-Baldvinsville libekwe irekhodi kwaye liye lakhupha ama-12 amabini amawele.
Imilinganiselo yokutya eyahlukileyo kunye nendlela efanelekileyo yokuphila ekugqibeleni inokukhokelela ekubeni amawele aya kuqala ahluke kakhulu ngaphandle komnye.
17. Amadala amadala ngo-2010 yayinguodade abaneminyaka engama-104 ubudala uAna Pugh noLily Millward baseBrithani. Kodwa ama-Edith Edith Richie kunye no-Evelyn Middleton bathabatha kuwo esi sihloko. Kwavela ukuba odade baseScotland babeziinyanga ezi-2 ezidlula amabritoni.
18. Awunakuze uve ngabantu abanjengoHunter Johansson, uMichael Kutcher okanye uPatricia Bundchen. Kodwa mhlawumbi uyazi iindwendwe zazo ezidumileyo - i-Scarlett, iAshton, iGiselle.
19. Nangona i-DNA yeamawele ayifani ngokungafaniyo, iimpepha zabo zeminwe azifani.
20. Phakathi kwamawele angama-left-handers aqhelekileyo kakhulu - kwi-22% yamatyala.
21. Kwi-15-20% yeziganeko zokukhulelwa, omnye kuphela weewele ezimbini ezisinda. Oku kubizwa ngokuba yi-twin syndrome.
22. Ininzi lamawele onke ehlabathini azalwe eNigeria, ubuncinci bonke baseChina.
Amawele omama, ngokwemibare, ahlala ixesha elide.
24. Iwele, ezisezantsi kwesibeletho, zibizwa ngokuba ngu "Child A", ngasentla - "Umntwana B".
25. Iibhere ze-polar ziphantse zizalise amawele.
