sorry about the repeated post, but now that i understand this X thing, I just went back and went thru the derby winners of the 2000's to see which of the four 'large heart genes' they trace back to and found that Big Brown and Giacomo are the only 2 that dont trace to any. Can anyone fact check me on that. Im pretty sure I dug pretty deep.
I added that info to my spreadsheet if you drag all the way to the right:
