Having recently received my brother's 12 marker results I've now upgraded to 67 but I'm awaiting the results. On the Whit Athey Haplogroup site the results of 12 markers were spot on for the Western Atlantic Modal Haplotype and continued going up to arrive at 92 Fitness score until I entered a 30 at DYS38911 and then it went right down to 81. Can anyone tell me how to interpret this, please?
