For several years we have known about 5 branches of the I-S20602 haplogroup:
I-A2512
I-Z17855
I-Y4460
I-S17250
and an unnamed I-S20602* branch represented by a single Big Y result for a man with ancestry from southern Poland.

This update shows a 6th branch, another I-S20602* man who has ancestry from Germany. He doesn't share any variants below S10602 with the Polish-ancestry man, or with any of the other 4 branches.

Until recently, A2512, Y18331 and Y18332 were considered to be equivalent SNPs. But according to a recent Big Y, a man with Greek paternal ancestry is Y18331+ but A2512-. His result for Y18332 is currently unknown. So now I-Y18331 is one of the 6 basic branches of I-S20602, and I-A2512 is a subbranch of I-Y18331.
