As I did state earlier, at least there would be some genetic boost in any eventuality on the crossing of the two branches. There is also a wider gene pool by accessing both branches, whereby one can combine complementary attributes. I would also believe that even one line-bred animal in the equation will contribute the line-bred genetic benefits to some degree while producing a calf that is growthier than the line-bred parent in many cases. Further, there are certainly a number of separate line-bred families to choose from for such a mating. For instance, consider the possibilities of mating Braxton Giants with Hazletts or Line Ones or Canadians.
