As fans of genetic genealogy, we are always interested in new applications. Here are a couple of articles about predicting appearance from a DNA sample:
Both of these articles feature a recent study that identified characteristics of a man who lived over 4,000 years ago. His blood type was A+, he had indicators for male-pattern baldness, dark skin, and was likely stout or square of build.
It may be that within years there will be genealogical applications for this. Could the future bring a DNA test that allows us to "see" some of our ancestors?
