When you do a close inbreeding..mother to son, father to daughter, brother to sister, you double the genetics of that line...the good and the bad. Lets say your dogs are Labradors....if there is dysplasia in the lines, there is a good chance that your pups will all have dysplasia...if they are both larger than breed standard, the pups will be too. If both parents are PRA positive (gene) then the pups will likely have PRA. If the parents both have outstanding temperaments, the pups will have super outstanding temperaments. Most breeders do years of research on their lines and still never attempt a close inbreed. Please learn all you can from your bloodlines before attempting to do a breeding like it COULD have disasterous results. Hope this helps and good luck :)
