If that is so, the how the heck did Minbari DNA get in fully-human Sinclair when he was scanned at the Battle of the Line long before his having ever come close to becoming Valen? No, it detected human DNA. When it was used to scan a Minbari, it detected remnant human DNA spread into their species from Valen, and when it was used to scan a human, it detected their human DNA.
EDIT: I see Ranger1 beat me to it while I was busy typing.
Could they have a Valen-class cruiser and a Valen-class destroyer? Heck, given what Dulann says about how obnoxious to a Minbari the Valen looks, maybe the Minbari revolted (not really, but you get the idea) and forced a redesign for what would constitute the Valen-class ships in order to fit their preferred aesthetic.
Was it specifically Human DNA or Sinclair's DNA? Sinclair's DNA would be the Human DNA that filtered through Minbari Society from Valen. Also, I thought I recalled it was only select HUmans the Trilum reacted to, so, therefore those Humans with Sinclair's families Genetic traits?
