Minimal reference J2 phylogeny

The makers of the mtDNA reference phylogeny (Mannis van Oven, et al.) did setup a “minimal reference” for the Y-DNA haplogroups. Team members are in contact with Mannis to achieve an updated and optimized J2-M172 minimal  reference: . Primary goals of

[…] optimal  global  discrimination capacity  based  on  a  strongly  reduced  set  that  includes  only  the  most  resolving  Y-SNPs. […]
(iii)  Y-SNPs  defining  terminal  haplogroups  that  have  an  (expected)  regional  population frequency of at least 2%, as determined from a population sample consisting of at least 50 unrelated males sampled in a geographic area spanning at least 100 km.
(iv) All Y-SNPs included in the reference tree need to be observed in at least five patrilineally unrelated males who do not have their genealogical origin in the same village. In this way, ‘private’ mutations that are specific to single families are avoided.
