knabe said:i think people get to crossed up worrying about relatedness when you should be really worried about phenotype and if sire is prepotent for his desirable characteristics that fit your breeding goals. too many full sibs out there that differ. yes there are ones out there that are similar, but if one wants to build for the future, and accumulate a phenotype, you are not going to get it easier by constantly outcrossing the pedigree while incrossing the phenotype. it's probably easier to breed type to type if pedigree is the same as the recombination patterns will be more predictable. it's pretty hard to increase the percentage of an individual without careful linebreeding that exceeds the initial cross offspring with something other than a sire daughter mating. the obvious thing to watch for is concentration of phenotype faults. ie, if something doesn't have the faults of the bull you are interested in, it's debatable whether the odds are increased for segregation of the faults if you bred the bull to something unrelated in the first place. not real sure why people don't see that concentrating even half sibs is difficult to match the original contribution of the makeup of an individual.
offspring of two half sibs would have the same contribution in the offspring as a full sire offspring.
two full sibs offspring would have same ratio as themselves, just recombined differently and biased towards phenotype of individuals, subject to recombination.
it's just a way essentially to create a new fullblood.
the problem of course is that every linebred animal is not worth keeping and must be under probably more stringent culling practices, which mostly probably doesn't happen too much anymore as numbers required to do this exceeds most breeders capacity or curiosity.
Whoa....You just blew my mind!!! Very nicely put.
