What each result means

A/A Two copies of the common allele. Published research associates this genotype with being able to smell the sulfur compounds that appear in urine after eating asparagus.
A/G One copy of the variant allele. Published research associates each copy of this allele with roughly 1.67 times higher odds of being unable to smell those compounds — a specific anosmia, meaning the sense of smell is normal for everything else.
G/G Two copies of the variant allele. Published research associates this genotype with the highest likelihood of not smelling anything unusual in urine after eating asparagus. Everyone produces the compounds; this is about whether you can detect them.
