Re: searching for the genetic differences between red hair and blon

Hi, Philip. I once read a piece of information, saying "The hair
color of the Hallstatt Nordic is characteristically and almost
exclusively blond, with ash-blond shades in one-third to one-half of
the cases, the remainder having golden blond to medium brown shades.
Rufosity is virtually absent. There is a small brunet minority, but
this may not necessarily have its origin in non-Nordic admixture.
One must assume that not all Nordics experienced an equal degree of
depigmentation.
The Nordic eye is typically light-mixed blue, with a large pure
light-eyed minority. Here also there is a small dark-pigmented
minority."

Could you tell me about the genetic differences between these two
colours?
I think blond-haired and red-haired peoples are different. What do
you think?

Excerpts from the book entitled Race, Language and Culture written
by Franz Boas and published by Columbia University Press in
November, 1939
"It does not seem to me justifiable to consider all the individuals
that are short-headed and brunet, although living in an area which,
on the average, is long-headed and blond, as belonging to the Alpine
type, and to explain their presence as due to mixture between the
two types. They may simply represent the remoter variations from the
long-headed blond type. This question has a most important bearing
upon the explanation of faces of social selection (pp, 537 et seq.)
by the assumption of different tendencies in the two types." What is
your opinion?

Thanks for your reply.
