Will the registry really help reduce the prevalence of lens luxation?
Using an open registry to select against a single recessive trait is effective if a significant number of dogs are registered, and if breeders follow a proven methodology for making breeding decisions based on the information in the registry. There are a number of documented cases where intensive projects such as the SIGHT registry have significantly reduced the prevalence of single-gene and even multiple-gene disease within several generations of dogs.
