According to a study published yesterday, Revisiting the harem conspiracy and death of Ramesses III: anthropological, forensic, radiological, and genetic study, Y- STR data places his YDNA haplogroup in E1b1a using Whit Athey's Haplogroup predictor:
"Genetic kinship analyses revealed identical haplotypes in both mummies (table 1⇓); using the Whit Athey’s haplogroup predictor, we determined the Y chromosomal haplogroup E1b1a. "
his DYS repeats are listed as follows:
| DYS 448 | 20 |
| DYS 438 | 10 |
| DYS 437 | 14 |
| YGATAH4 | 13 |
| DYS 392 | 17 |
| DYS 391 | 8 |
| DYS 393 | 8 |
| DYS 385a,b | 20 |
| DYS 19 | 19 |
| DYS 389II | 33 |
| DYS 390 | 21 |
| DYS 389I | 13 |
| DYS 456 | 13 |
Plugging these numbers in Whit Athey's predictor does indeed indicate that his haplogroup is E1b1a with 99.1% probability using equal priors. The decisive DYS, to judge between E1b1a and E1b1b, is DYS 390, with the exclusion of DYS 390, his haplotype belongs to 83.7 % E1b1b and 15.8% E1b1a, however, it is well known that DYS 390 = 21 is a high probability signature for West/Central/Southern Africa, i.e. where E1b1a dominates (see below).
