What do you mean by "unbroken path"?
Any animal that has the following sires in its pedigree is suspect for HY:
Justa 425E Mainline 680K
FHR Genetic Giant
RWJ Victor J3 212
LS Beau Victor 1 30
JR Nick The Butler P183
FOF WF 3N Tanner A36
These bulls would be ancestors to A LOT of Hereford genetics, both polled and horned.
Take for instance, progeny of GK Genetic Explosion. He "breaks the path" back to LS Beau Victor 1 30 (a known HY carrier) because he is tested "free" or HYF. The path is LS Beau Victor 1 30 (HYC) sire of GK Beau Miss 269G dam of Explosion sire of GK Genetic Explosion sire of "progeny". The 269G cow and Explosion bull are untested to date so they have some odds of being carriers (50% and 25% respectively).
Some "path breaker" bulls:
MM RSM Stockmaster 512
WTK 55Y Bond 75A
Kilmorlie Deliverance ET 80U
Feltons 517
Feltons Endurance 745
Feltons Domino 774
GK Varsity S61
RRH Mr Felt 3008
Gerber Voyageur 80X
Haroldson Raider P183 2Z
