What percent of DNA is different between a Caucasian and an Asian?
October 27, 2006:
I am descended from Eastern European Ashkenazi Jews, which are known to be at a much higher risk than all other groups to have genetic mutations and are carriers for diseases such as Tay Sachs and Cystic Fibrosis. They also have a higher risk than the general population of other diseases such as breast cancer, PCOS and diabetes.
I am extremely curious to find out, what did my ancestors do to develop such gene mutations and diseases? Did marrying close relatives cause it? I doubt it because Sefardi Jews also marry often within family and don't have any of the above diseases.
Is it possible for the current generation to cure the mutations or at least prevent it from spreading?

Is it possible to identify a racial origin such as Native American?
July 14, 2004: I have read, "Genetically speaking, nothing differentiates one race from another. All humans share the same set of genes. There is no African gene, no Caucasian gene, no Asian gene." However, I also understand that there are genetic markers such as mtDNA haplotype L1, L2, L3, M, N and etc. that indicate a person's origins. In light of this, isn't it possible to determine "race" through DNA analysis?
