So, here's something that I'm really interested in finding the answer to.
As some folks here know, my son is a geneticist working on his post doc in developmental heart research. To me, a few of mine have Secretariat in their lines.
Anyway...the question. Was it Blue Larkspur that threw the mutant gene for the enlarged heart? I think so, but my son and I have gone round and round on this. Your input would be greatly appreciated to resolve this developmental biology debate. What do you think?
btw, Alydar was a better broodmare sire than either Spectacular Bid or Affirmed imho.
Thanks,
DTS

I will defer to Balletto or Pedigree Ann for this one. You might want to take a look at Bill Nack's Secretariat book too, if you haven't already. He provides a TON of info on Big Red's pedigree, and it is just a really good book.
