Of course, the paper trail doesn't affect the DNA. The Y-chromosomes
will be what they are, regardless of whether the paper trail is weak
But I think your real question concerns what we expect to find in two
people with a recent MRCA. Specifically, their Y chromosomes will be
virtually identical. And ALL differences between two Y chromsomes
must have to have happened after their MRCA, so I think the answer to
your question as you asked it is ""yes".
