apparently dogs with one allele for the mutant myostatin gene are fast dogs with out having the extreme appearance of the bullies
naturally a breeder would choose to breed fast dogs, and preferably to breed a fast dog to a fast bitch. If the "bully" mutation is a factor in the dogs' speed they are likely to have some offspring which have a pair of mutant genes and exhibit the undesirable extreme bully makeup. so selective breeding is definitely a factor
the NY Times article was more about the use of DNA testing by dog breeders than about the details of "bully" genetics
DNA testing could be useful in ruling out serious inherited diseases but doesn't sound like a good idea for other characteristics as a good dog is a combination of many factors and many different genes. One breeder quoted wanted to exclude chocolate poodles from her gene pool. I thought that was extremely silly. By ordinary selective breeding she can probably get mostly blacks and the chocolate pups will still be acceptable in the show ring and desirable to some of the people who want to buy poodle pups -- and what other good characteristics might be weeded out along with the chocolate gene?
