A moonlight cruise on Lake Michigan, along the Chicago shoreline was provided on Saturday night. While I'm not a big fan of big cities, I greatly enjoyed the view of Chicago at night. The convention broke up on Sunday morning. We all left happy, refreshed and exhilirated, having spent time with old friends and made new ones. Twin pregnancies are either fraternal or identical.
Fraternal twins share the same womb, but come from different ovum.
Genetically, fraternal twins are as alike as any pair of siblings. Identical twins on the other hand, come from the same fertilized ovum and theefore share the same genetic makeup. The ratio of fraternal twin to single births varies from country to country. The highest incidence occurs in the Yoruba tribe of Nigeria where 46 of every 1000 pregancies involves fraternal twins. The lowest is in Japan, where the incidence of fraternal twinning is 4 per 1000.
