ISOGG provisional markers

[vettor]

What are Provisional markers in ISOGG and how long do they stay in this state?

[GTC]

Provisional SNPs are color coded purple and defined as: SNPs newly submitted to the ISOGG committee that have sufficient information to be at an approximate tree position but require better evidence for exact placement.

thanks

But I my interest is because in one branch of my tree that I pass through to get to L446 , I am positive for the provisional marker but negative for the other 2 markers ( there are only 3 markers on that branch )

For specific questions on the T tree I would suggest contacting the person who maintains it:
