of the families with retinitis pigmentosa (RP) showed segregation with two microsatellite markers on chromosome 3 listed in
descending order from the centromeric end. Squares indicate males; circles indicate females; slashed symbols indicate deceased;
solid symbols indicate affected; open symbols indicate unaffected.
