Are light traits in Southern Europe due to the northern European admixture ?

[Baluarte]

For what I've seen, the lightest eyes eyes they have are medium or light brown, like that girl.

[Peyrol]

It depends also by population...i know some pure quechuas with almost black eyes...while some amazonians can have hazel eyes like this girl...don't mention also to the guaranì from the Chaco Paraguayo, but many of them are mixed with chaco germans so they aren't ''pure''.

President Alfredo Stroessner was 1/4 guarani himself and had azure eyes

what about the diffusion of the gene for lactose digestion ? it seems that before the bronze age it was even less widespread than today in Southern europe

I don't know about the particular gene, but Iberia does seem to have lower levels of lactose intolerance than most of the rest of southern Europe:

^ Source of that map?

[Jackson]

Don't know actually, i'll see if i can find a more reliable one.

That map shows the frequency and spread of the lactase persistence T-13910 allele of the LCT gene. HARDLY reliable.

EDIT Here is a map showing lactose persistence phenotype frequencies.

Apparently it lacks samples from the Balkans and South Eastern Iberia, so it could be wrong.

[Lábaru]

Is normal that Iberia to have a high tolerance to lactose because genetically is the area of ​​southern Europe with more genes from central/Atlantic area and northern Europe.

Anyway every map says something different, not very realiable.

[Übermensch]

There are also indigenous people with mixed/light eyes...

I suppose that's for european spanish influence...
