Skin color gene identified (NYT and Science report)

AI Thread Summary
A recent article in the New York Times highlights a significant finding in genetics: a single gene is a major determinant of skin color, with 99% of European Caucasians possessing one allele and 93% of Sub-Saharan Africans having another variant. The discussion raises questions about the scientific implications of this discovery. While some view it as a potential marker for race, others consider its applications in fields like forensic science and genetic engineering. The possibility of using this gene for "designer baby" technologies is mentioned, suggesting that parents could select traits such as skin color. However, the overall significance of identifying this gene is debated, with some arguing that its implications may be trivial in the broader context of scientific advancement. The potential for reconstructing an individual's appearance from DNA is also noted as a future application.

Yesterday's issue of Science magazine, and this article in the 16 December NY Times report that a major determinant of skin color is a single gene which has been located

reportedly 99 pecent of European caucasians have one allele, one variant of the gene, and some 93 percent of subsaharan Africans have another variant.

I haven't seen the Science article, maybe someone who has can make this more precise. What I see in the NY Times doesn't quite make sense to me and I would like to hear some elaboration.

Hi Ian, I remember you as especially informed and objective from earlier discussions. I don't get in here much.

I was wondering. Can you indicate what the scientific significance of this might be?

I cannot see much importance. the gene does seem to be a race marker----something where 99 percent of a european caucasian population has one allele and over 90 percent of a subsaharan black population has the other allele.

I suppose the discovery might find application in some kind of "designer baby" technology----if kookie parents wanted their child to have, say, dark skin and blond hair and blue eyes, then they could presumably have some laboratory switch the allele at just one site. the results might be startling, perhaps disturbingly beautiful.

but these are kind of trivial consequences, it seems to me, in science terms.

do you think of any advantage in science terms of having identified this site?

I didn't look at the paper yet, but imagine the benefit for forensic investigations.

Better yet, imagine in a few years being able to fully reconstruct the visual appearance of an individual just from the DNA.

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
