How Big Are the atDNA Databases?
Some DNA testing companies report their databases sizes periodically while others don't publish their numbers at all.  We can estimate the latter by comparing how many matches we have at the former.  Screenshots show how to access the information at each testing site from a computer. If you haven't tested at a company, skip the question.
