[QUOTE="WalnutCrest, post: 1159348, member: 21715"] If a two-way cross stabilizes at 66% heterosis ... and ... a three-way cross stabilizes at 83% heterosis ... does a four-way cross stabilize at about 90% and a five-way cross at about 94%? In other words, is Nesikep's "perpetual cross" herd (i.e., an unbroken string of X number of new breeds of bulls) going to run close to 100% heterosis? So, if maximizing your heterosis is the goal, one should look to bring in blood that is as unrelated as is reasonably possible to your existing herd ... while maintaining as consistent phenotype as possible ... right?
