  1. Results from sequencing FGF20 exon 3 in 38 sc/sc individuals, 9 sc/+ individuals and 40 WT birds. The FGF20 c.535A > T mutation was found in all of the sc/sc and none of the WT samples sequenced. The genotype of the two flanking SNPs (rs14481412 and rs14481413) revealed that 25/40 WT individuals were homozygous for the same haplotype as scaleless, indicating that the FGF20 c.535A > T mutation does not lie within a rare haplotype.
