From my Chatbot:

"Consumer ancestry tests do NOT analyze more DNA for Native American ancestry than for any other population.

They use the same SNP chip — typically 600,000 to 1,000,000 SNPs, which is about:

$$\frac{\mathrm{1,000,000}}{\mathrm{3,200,000,000}}\approx 0.03\mathrm{\%}$$

So, the amount of DNA examined is ~0.02–0.03% of the genome, regardless of whether the comparison is Native American, European, African, or anything else."

Next time you hear a genetic analysis, this is why it is bullshit.
