L342 is subject to recombination

[Boromir]

lgmayka had placed couple months ago on another forum (http://eng.molgen.org/viewtopic.php?f=77&t=571) the following info:


In the R1a1a and Subclades Project, kits 127747 and 72455 are close enough at 67 markers to suggest common SNP status and subhaplogroup membership. Both are Z94+ , but 127747 tested L342- whereas 72455 tested L342+ . I asked Thomas Krahn to check the accompanying SNPs L319, L348, and L349 for each one. He replied:
---
Kit 72455 is just normal (L319, L342, L348, L349)+. However kit 127747 looks very unusual (L340, L343, L344, L346, L354, L355, L356, L357, L358, L359, L360, L361, PR4337)+

It seems to me that the (L319, L342, L348, L349)+ pattern has been overwritten with yet another recombination event.

Apparently this chromosome segment is particularly susceptible to recombination.

I have asked Mr. Krahn to similarly check the other two Z94+ L342- (kits 195023 and 210881) but he has not yet responded.

lgmayka, have you got the answer on your question about kits 195023 and 210881? If yes, can you share, please?

Unfortunately, no. Thomas Krahn has not responded to multiple requests in this matter.

Thank you very much, Larry.

You know that Thomas Krahn still keep "magnificent" four (L319, L342, L348, L349) and Z94 on the same level on his draft (http://ytree.ftdna.com/index.php?name=Draft&parent=8819763). Doesn't it mean that haplotypes mentioned in your question to Thomas have the same recombination event in the vicinity of L342 as it happened in case of kit 127747?

I also wasn't able to convince Igor Rozhanskii to place L342 under Z94 on his R1a cladogram (http://r1a.org/index.htm). As you know he and Anatole Klyosov build there R1a tree based on STR analysis. Igor replied that he doesn't have enough data yet.
