Data for QTL mapping on brain size in sticklebacks

The data set is used in a quantitative trait locus mapping study on six brain volume traits including bulbus olfactorious, telecephalon, optic tectum, hypothalamus, cerebellum and total brain size of a F2 nine stickleback population. The data consists of 239 individuals, and 15198 non-identical SNPs. A linkage map has been constructed, and divide the SNPs into 21 linkage groups. The data are distributed as following: File1: brain_phenotype.txt -The phenotype data of six brain traits, which have been corrected by the sex and bodysize effects. File2: genotype.txt -The SNP data, each row represents the individuals which is one-to-one match to the phenotype data file, and each column represents the SNPs which is one-to-one match to the linkage map file. The missing genotype data have been imputed, and coded as 1,0,-1 for the genotypes AA, AB and BB, respectively. File3: linkage_map.csv -The linkage map information, column1 is the marker ID, column2 is the linkage group info, and column3 is the linkage position of each SNP
