If this defective gene was the one that stabilizes our animal during stressful situations we end up with a nervous dog. If the defective gene was one that coded for genes that protect against cancer we have a dog less likely able to fight cancer. With many double defective genes the problem may be so severe that the animals die, suffer debilitating disease. Some are doubled up on defects in bone structure, reproductive anatomy, immune function, or may be blind, deaf, or plain sick all the time. What we are seeing whether the breeder of a particular line acknowledges it or not is that when the overall homology (increased Inbreeding Coefficient?) of a specific germ line is focused by line or inbreeding there is an exacerbated tendency toward occurrence of disorders that are ultimately controlled by multiple sets of genes. Of particular interest cosmetically in the APBT are kinked tails, underbites and serious debilitating disorders as hip dysplasia, temperament issues (such as fear or human aggression), and congenital heart anomalies. Of utmost importance to an APBT breeder is prior knowledge of abnormalities that the common ancestors have produced. Continued linebreeding within such lines can promote the fixation of these defects permanently within the line resulting in extraordinary risk of genetic defects....to continue reading this article please click on here...
