I’m sure DYS487=13 I1xL22 will not all be Z138+ and Z139+. But one clade of 487 = 13, I1-ESc-13, probably is. I have described i1-ESc-13 extensively last night and earlier today. I noticed the other two I1xL22 with 13 at 487 ---- AS10 and AS1313 --- don’t seem to have any of the new Z series snp tests. I’d recommend Z138 and/or Z139 for members of these two clades as well as I1-ESc-13 clade as earlier discussed. Ken
