Post your blond hair snps

You are also a carrier! It might come from your Iberian or Italian ancestry because it more frequent in Southern rather than Northern Europeans unlike the other red hair carrier variants. It is similar or even slightly higher in penetrance to rs1805008 (82.43 vs 75.19 OR with red vs dark hair for UK Biobank according to this study: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6548228/) which user Grace is a carrier of. She also has a reddish element to her hair so it is not surprising that you do too.

Now that i checked it definetely comes from my maternal grandma!

she also got A/G and so does my mother.

interesting.

rs11547464? It is a rare red hair carrier MC1R variant......

rs11547464 G/G

rs12821256(C;T) --> C allele has a significant lighter hair effect,... rs12896399(G;T) -> T allele correlated with lighter hair color and a higher chance for blue eyes...rs16891982(G;G) -> G allele associated with lighter pigmentation, T allele increases change of black hair...

rs12821256 C/T
rs12896399 G/T
rs16891982 C/G


Interesting. I guess this means that if I marry a blonde or redhead woman, my children will largely look like their mother.

I strongly suspect that the distribution of that variant is associated with that of EEF admixture. Poles still have a large amount of EEF admixture (~43%) but significantly less than Iberians (~60%). Among Finns the presence of the variant is negligible (allele frequency of only 0.001112 for gnomAD v4.0) but that could be impacted by their population bottleneck in addition to being at the low end of EEF admixture for Europeans. For the Estonian aggregate with gnomAD v2.1.1 the allele frequency is 0.004151 similar to Swedes and not so far below Northwestern Europeans, so the Finnish bottleneck is likely quite relevant for the significant difference.

Arg142His is a rarer variant so even if the allele frequency among Southern Europeans is around twice that of most Northern Europeans the absolute difference in frequency is not that much.

You definitely are a carrier of the major blondism variant rs12821256, but G is the reference allele for rs11547464 so not a carrier:

According to most trait reports (23andme AncestryDNA etc.) I have like 10% chance for blonde hair but 1% chance for red hair
