Шта би тачно била ова NO2 представљена на графикону?
У поменутом раду Toomas Kivisild, The study of human Y chromosome variation through ancient DNA, May 2017, Volume 136, Human Genetics (
https://link.springer.com/article/10.1007/s00439-017-1773-z), у поднаслову Genetic history of Eurasian Y chromosomes, аутор пише о NO2 слиједеће:
"The zoomed in version of the sub-tree relating Oase, Ust’Ishim with extant variation of the N, O and NO2 clades is shown with branch-defining marker names [modified from (Poznik et al. 2016)] next to the geogrpaphic map displaying the locations of the four ancient sites. The colour-coded distribution of Y chromosome haplogroups in present day populations ignores cases of recent admixture.
Haplogroup names here and in other figures follow the nomenclature suggested in Karmin et al. (2015)"
Karmin et al. (2015) јесте рад под насловом: A recent bottleneck of Y chromosome diversity coincides with a global change in culture. Genome Res (
http://genome.cshlp.org/content/suppl/2015/02/18/gr.186684.114.DC1/Supplemental_Figures.pdf), гдје на 13. страни појашњења допунских табела пише:
"Figure S13. Refined topology of the basic branches of the Y-chromosome tree with an emphasis on the short branch lengths defining haplogroup F sub-clades. Mutation counts and branch defining markers (included in counts) are shown on the branches. If no previously named mutation existed on a given branch, a name from the B-series was given to one of the mutations discovered, and the rest were denoted with _eq in the annotations table. Branch lengths include recurrent mutations if such are present in no more than two (exceptionally three) locations in the Y-chromosome phylogeny. Given comparative data from Malaysian high coverage sequences (Wong et al. 2013), we map the position of the F2 clade represented by Malay sample SSM072 and redefine haplogroup NO by F549 and 4 equivalent mutations.
NO splits further into NO1-M214 and the novel NO2-F2755, as defined by the SSM016 sequence."
Према Кармину и осталима NO2 би представља предлог нове гране NO, NO2-F2755, дефинисане SSM016 низом.
Такође треба примјетити на страни 9 табелу Figure S9. Coalescent times of the oldest Y chromosome haplogroups outside Africa, потпуно идентичну у идејној основи, приложеној табели Томаса Кивисилда, са образложењем о приказу 11 додатних грана у испрекиданим линијама, које се односи и на поменуто NO2: "The plausible branching structure of 11 additional branches that have been reported in the literature is shown in dotted lines".
