I bought an Ancestry DNA test and downloaded the raw data and put it into a database. It said that at rs1393350 I have A, A, and said that this was rare (0.63% of the population) and I had an increased risk of melanoma. It showed me a chart that put me quite a bit into the danger zone, and now I am really scared!

I’ve heard that no one has the exact same DNA except for identical twins. But Ancestry.com DNA tests showed that my sister, mother, and I have the same DNA breakdown (100% Eastern European). My sister and I are not twins. What is the reason for this similarity? Should my other siblings take the test, too?

I belong to 23andMe (DNA testing site) and have always wondered why it said I am more likely to have blue eyes. They use SNP: rs1393350 where I am a GG and rs12896399 where I am a TT. However, I have dark green eyes. Why do my SNPS that determine eye color basically say I should have had blue eyes when I clearly do not?
