Linkage mapping genotypes dataset

Genotypes used to produce a linkage map of 11 RAD-Seq derived markers flanking the shell colour (C) and banding presence (B) loci of the Cepaea nemoralis supergene. Data for two crosses are shown: C100 x C101 was a cross between a double homozygous recessive yellow-banded mother and a heterozygous father, resulting in either yellow-unbanded or pink-banded F1 offspring (n = 102). C118 x C119 was a cross between a double homozygous recessive yellow-banded parent and a pink-banded parent heterozygous for colour, but not banding. Full details of the crosses and the genotype assays are provided in the paper. Marker genotypes are provided in CRIMAP formatting.
