Hi Doris! No need to apologize! Your concern is valid that's why we need to discuss everything. Assuming that all of us will avail of the testing, there are three categories to which our dogs will be classified. 1) CLEAR 2) CARRIER 3) AFFECTED. CLEAR- A dog has 2 copies of the normal gene and will neither develop Early-Onset Hereditary Cataract, nor pass a copy of the Early-Onset Hereditary Cataract gene to any of its offspring. CARRIER- A dog has one copy of the normal gene and one copy of the mutant gene that causes Early-Onset Hereditary Cataract. It will not develop Early-Onset Hereditary Cataract but will pass on the Early-Onset Hereditary Cataract gene to 50% (on average) of its offspring. AFFECTED- A dog has two copies of the Early-Onset Hereditary Cataract mutation and is affected with Early-Onset Hereditary Cataract. BELOW ARE THE SCENARIOS OF BREEDING CLEAR dog to a CARRIER dog and a CARRIER to CARRIER breeding. CLEAR (XX) will be bred to CARRIER (XY) possible offspring = XX, XY, XX, XY (50% of the pups will be CLEAR and the other 50% will be CARRIER) CARRIER (XY) will be bred to CARRIER (XY) possible offspring = XX, XY, XY, YY (25% of the pups will be CLEAR, 50% will be CARRIER and 25% will be AFFECTED) My suggestions: If an individual decides to do this breeding (CLEAR to CARRIER and/or CARRIER to CARRIER), their offspring will be subjected to genetic testing to identify which pups are CLEAR, CARRIER and AFFECTED. It would be wise for an individual to breed CLEAR to CLEAR since there's no need to test their offspring for the EOHC, meaning no added cost for the testing. If our club will be established, I'm proposing that we create a HEALTH COMMITTEE, similar with that of the BTCA, that will issue health certificates to all dogs owned by the club's members. In the health certificate will include if the dog is clear of EOHC either by lineage (both parents are CLEAR) or by testing. In the future, we may also add requirements for patellar luxation, Hip Dysplasia testing etc. It may sound expensive and too much to ask. Yes, but we may start from one then add another and we will put a time frame until everyone is ready for this. For example, Let us all agree that by year 2012, our dogs should have been tested for EOHC, then by 2013 we will be requiring the patellar luxation examination and so on and so forth. I will try to be in Manila by the month's end so I can share more my views and suggestions. For the meantime, keep on posting! Everyone is encouraged to participate, this is a no-holds-barred discussion and be open. walang personalan kumbaga.
