Puzzled how this Ancestry logic can be logical!

Re the original question and particularly the Dan Alfie

I came across a case a few years ago which could be another possibility.

" A father and son " on paper were actually brothers elder brother bringing up a younger "surprise" baby
With 2 brothers there can be one has inherited part of the jumble that makes up your DNA

Does that just give sotmethng else to think about

The Ancestry to Ancestry tests for Dan and Alfie show 3488 cM share. Their MH to MH show 3534 cM
Dan's uncle has also tested but just on MH, the share with Dan on there is 1537 and 855 with Alfie.
