Three independent pedigrees demonstrating autosomal recessive inheritance of mutations 1, 2 and 4 in FGF5 with the long-haired trait.
A= Two-generation portion of the non-breed Nestlé-Purina pedigree.
B= Two-generation portion of the non-breed John Hopkins University pedigree.
C= Three-generation pedigree of long-haired Ragdoll cats.
Square = male, Circle = female. Open symbol = short-haired, filled = long-haired.
The identification number of cats is written over top of individual symbols. Coded genotypes are listed in parentheses: N= no mutation, 2 = Mutation 2 (c.C>T406), 3=Mutation 3 (c.del474T), 4 = Mutation 4 (c.A>C475)
