Brain measurements of nine-spined sticklebacks

Brain measurements together with population, habitat, sex and treatment information

Stickleback

This file contains the primary data underlying the publication, that is, three-spined stickleback brain (and body size) measurements. The second tab in sheet contains some explanations for abbreviations used in the header columns

Metamorphs body weight

143 metamorphs (four to five per tank) were used for analyses. Formalin fixed metamorphs were weighed with a digital balance

Genotype data

"Genotypes Noreikiene et al.xlsx" contains genotype information (10 polymorphic microsatellite markers) for individuals analyzed in the study and their parents (30 dams and 15 sires). Genotype information was used to assign offspring to their parents and construct a pedigree, which is also given in the file. More details are provided as comments in the file

Brain region and total brain volume data

"Data file Noreikiene et al.xls" contains information on brain region (bulbus olfactorius, telencephalon, tectum opticum, cerebellum and hypothalamus) volumes and total brain volume, which were estimated using the ellipsoid model in three-spined sticklebacks as described in the paper. Also, the data file provides information on the sex and body size of individuals used in the study, their pedigree information and treatments they were exposed to. More details are provided as comments in the file

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 SN
