DNAprint Genomics (DNAG)

[frogdreaming]

mingwan0,

I appreciate your valued response. The point that I was trying to make with the 'disconnect' phraseing is that there is not a direct causal linkage between hair color and genetic makeup.

Your response further confirms that premise when you indicate that such other factors have an impact.... [aging, pathological reasons, biochemical reasons, minerals, chemicals, trace elements, drugs, heterochromia, etc (not to mention shaving].

My contention is that it will be impossible for the basic DNAP technology, of perusing anonymous DNA samples for representative SNP patterns, to ever come up with a direct and accurate prediction of hair color. Many other factors must be assessed and included in the final analysis. Such assessments and analysis is not a part of DNAP's expertise.

best regards,

p.s. Since you included mouse studies in your response I am whimsically including the following link. Although it is probably irrelevant, it shows that the connection between DNA and pigmentation is not as direct as we seem to think it is.
