DYS     Numbers

D = DNA       Y = Y chromosome       S = a unique DNA segment.
The markers in red have shown a faster mutation rate then the average, and therefore these markers are very helpful at splitting lineages into sub sets, or branches, within your family tree.

DYS-393

DYS-390

DYS-19

DYS-391

DYS-385a * DYS385a/b are unique. They are duplicated on the Y chromosome, and each copy can
DYS-385b mutate independently.

DYS-426

DYS-388

DYS-439

DYS-389I is part of the larger DYS389II. You can think of it as DYS389I is the first part, and
 DYS-389II includes that first part and more.

DYS-392

DYS-389II For matches at DYS-389II you're looking for the differences between DYS389I and
DYS-389II being equal for both persons.
DYS-458

DYS-459a * DYS459a/b are unique. They are duplicated on the Y chromosome, and each copy can
DYS-459b mutate independently.

DYS-455

DYS-454

DYS-447

DYS-437

DYS-448

DYS-449

DYS-464a * For the DYS464 system each are unique and each copy can mutate independently, some DYS-464b people have even more than four copies.
DYS-464c
DYS-464d


Haplogroups defined by the 12 UEP markers according to a nomenclature modified from Rosser et al. (2000) and Weale et al. (2001)  The correspondence between this nomenclature and that proposed by the Y Chromosome Consortium (2002) is as follows:

 hg1 = P*(xR1a)
 hg2 = BR*(xDE,JR)
 hg3 = R1a1
 hg4 = DE*(xE)
 hg7 = A3b2
 hg8 = E3a
 hg9 = J
 hg16 = N3
 hg20 = O2b
 hg21 = E*(xE3a)
 hg26 = K*(xL,N3,O2b,P)
 hg28 = L, hg29 = R1a*
 hg37 = Y*(xBR,A3b2).
