The Start of the Backcross Project
In 1973 Dr Robert Schaible mated a Champion Pointer to an AKC registered Dalmatian bitch in order to get a copy of the gene for normal uric acid. This was the one and only time a Pointer was used in the Project. The pups were all Uu as would be expected. Noot Lizzy: ze dragen dus het recessive gen maar produceren normale urine. They were also far from typical Dalmatians. He chose a single pup from this litter and bred again to an AKC-registered Dalmatian (Uu x uu). Uu is dus een kruising Pointer x Dalmaat. En uu is dus een "echte Dalmaat". The resulting pups from such a breeding are, on average, half Uu and half uu. Those that are Uu carry the recessive gene, but produce normal levels of uric acid.
