13. Amathuba okubeletha amawele owesifazane ekunceliseni ngesikhathi sokukhulelwa izikhathi ezingu-9 eziphakeme kunomama ozayo esikhathini esizayo.
14. Candida Godoy, eBrazil, iyinhloko-dolobha yomhlaba wamawele. Abashadile bazalwa lapha ngo-8% wabo bonke abakhulelwe. Ososayensi bavame ukukholelwa ukuthi isakhi sekhethelo esithi "amawele" senziwa lapha ngabafuduki. Futhi waphumelela ngokuqinile, njengoba ubona.

20. Phakathi kwamabili amawele abashiywe abavame kakhulu - kuma-22% amacala.
21. Emaphesenti angu-15-20% okukhulelwa, amawele amabili kuphela asinda. Lesi simo sibizwa ngokuthi i-twin syndrome ephikile.
