My rs6625163 geno is `(A)` (as per 23andMe) instead of `(A;A)`. What does that mean? --Mathiasbynens (talk) 12:13, 22 April 2015 (UTC)

It means you are male and only have 1 X chromosome.
What I meant was, should I assume the result is equivalent to http://snpedia.com/index.php/Rs6625163(A;A)? Should I create a separate page for http://snpedia.com/index.php/Rs6625163(A)? Or is the notation (A;A) equivalent to (A) already?
it is not rigorously defined, and you'll see a bit of each in SNPedia. Yes, you can treat it as equivalent to Rs6625163(A;A). However I'm gradually settling on the idea that rs1234(A;A) should be read as "at position rs1234 there are only A genotypes". Creating the extra page wouldn't have any obvious benefit. --- cariaso 15:14, 22 April 2015 (UTC)
