What do the colors (highlights) mean on the reports?

On the summary reports and in the genotype sections of articles, you'll notice that your genotype is sometimes highlighted.

• A yellow highlight indicates that your genotype matches one copy of the effect allele (heterozygous).
• An orange highlight indicates that your genotype matches two copies of the effect allele (homozygous).
• A green highlight shows you that your genotype matches to the effect allele, and that the effect is generally positive.

The highlights are simply a visual way to let you know to read the Note About the Effect Allele.

Sometimes you'll notice that a positive effect is still highlighted with yellow or orange. In those cases, the SNP usually has both positive and negative effects, depending on the context. For example, a SNP may help someone resist getting the flu, but it may also increase the risk of chronic inflammation.
