Do people who look different of the same different cluster differently?

[7eleven]

For example, a Greek who is 100% Greek but looks more Mediterranean arab and a Nordic looking Greek. Or an Armenoid Jew vs a Nordic Jew. Or a Nordic German vs an Alpine German.

[Sargon999]

No, I do not think so. Those varieties can be prevailent in the same family.

[Ashina]

If one Greek family (father, mother, siblings, uncle, grandpa etc.) is Nordic looking and the other family is Middle Eastern looking, then there is a good chance that they cluster differently.

[AlexDelarge]

Populations all cluster together no matter how they look like. Blonde spaniards don't cluster next to brits or germans and dark looking irishmen don't cluster next to spanish or italians.
If people clustered according how they looked then euro plots would be a mess and very difficult to read. But looks is not the same as genetics.

[Svin]

This is rubbish. I look primarily English, but cluster with Central Italians. Alex and Sargon are right. Both Europeans and even many Middle Easterners already have great diversity in terms of colouring and pigmentation, when looking at their ancestors. The family of Humanist is a good example.

Genotype isn't the same as phenotype so the answer is no.
