  1. Chromosome 4 and 20 QTL controlling mean ventral row 1 to 3 gill raker number in three marine × freshwater F2 crosses. Chr.: chromosome, LOD: logarithm of the odds, PVE: percentage of phenotypic variance explained. Phenotype means and standard errors are given by genotypic class of F2 (MM is homozygous marine, MF is heterozygous, and FF is homozygous freshwater). Additional information on the properties of these QTL is presented in Additional file 8: Table S3.
