Hello
I asked some simple question to 23andme(about the difference between 99 and 199$ option), but I got an answer that I don't understand(maybe because english is not my main language), maybe someone could help me understand this? Here's the answer:
"Hi X, 23andMe performs genotyping, meaning that we look at specific positions along your genome that are known to differ between individuals. These positions are called SNPs (Single Nucleotide Polymorphisms). Many of these SNPs are incorporated into our reports. Our customers can view and download their uninterpreted data from the genotyping analysis in its raw format (your A's, T's, C's and G's) within the Browse Raw Data feature. The Browse Raw Data feature is available in both the Ancestry Service and Health + Ancestry Service. However, we do not provide a preview of the Browse Raw Data feature as this data is only suitable for informational use and should not be used for medical purposes. 23andMe raw data has undergone a general quality review, however only a subset of markers have been individually validated for accuracy. For this reason, if receiving raw data is your primary goal, we cannot recommend that you purchase our service. Hope that helps! Best, 23andMe"
