Classification as individual having
fair-dark or red-blond-brown-black hair


Step 1: Choose populations

2 populations (fair or dark hair), rs1129038-12913832 haplotype

2 populations (fair or dark hair), no haplotype

4 populations (red, blond, brown, or black hair), rs1129038-12913832 haplotype

4 populations (red, blond, brown, or black hair), no haplotype

Step 2: Choose classifier

Naive Bayes (Hardy-Weinberg principle applies)

Multinomial logistic regression

Genetic distance algorithm

Step 3: Data input

Type 12 markers of the individual to classify as appropriate. For the required (rs) numbers, see graphic on left. For instance, the following 12 marker profile would be valid in the case of 2 or 4 populations:
