Lauren,

I'm not convinced that the Rasmussen Factor is necessarily causual. I don't believe that inbreeding to a mare, say 4 x 5 is a particularly notable thing in isolation. I suspect what often happens is that mares, their daughters and half-sisters get bred to the same stallions, and other stallions from the same sire line, so you get inbreeding and linebreeding to similarly bred horses.

Alan,

As you know, inbreeding to a superior female within 5 generations through different individuals is called the Rasmussen Factor. CONCORD POINT is a beautiful example of the RF, as he's inbred to the high-class stakes winner, Foggy Note, through her daughter, Moon Glitter and her full brother, Relaunch.

It's no mistake that Concord Point has high quality. More often than not, it has been proven that the RF inbreeding pattern is a powerful method for mating Thoroughbreds.
