3. Few Clues About African Ancestry To Be Found In Mitochondrial DNA
   10-14-2006 · ScienceDaily
   Mitochondrial DNA may not hold the key to your origins after all. A study published today in the open access journal BMC Biology reveals that fewer than 10 percent of African American mitochondrial DNA sequences analysed can be matched to mitochondrial DNA from one single African ethnic group. The current study suggests that only one in nine African Americans may be able to find clues about where their ancestors came from, in their mitochondrial DNA.

   02-21-2007 · EurekAlert!
   Researchers suggest a reason for racial disparity in breast cancer survival rates. African and African American women are much less likely to survive breast cancer surgery than their white counterparts and far more likely to get the disease before the menopause. Previous research suggests that those who undergo surgery for the disease before the menopause are more prone to relapse.
