| Summary: | Feral animals represent an important problem in many ecosystems due to interbreeding with wild conspecifics. Hybrid offspring from wild and domestic parents are often less adapted to local environment and ultimately, can reduce the fitness of the native population. This problem is an important concern in Norway, where each year, hundreds of thousands of farm Atlantic salmon escape from fish farms. Feral fish outnumber wild populations, leading to a possible loss of local adaptive genetic variation and erosion of genetic structure in wild populations. Studying the genetic factors underlying relative performance between wild and domesticated conspecific can help to better understand how domestication modifies the genetic background of populations, and how it may alter their ability to adapt to the natural environment. Here, based upon a large-scale release of wild, farm and wild x farm salmon crosses into a natural river system, a genome-wide quantitative trait locus (QTL) scan was performed on the offspring ... : phenotype_genotypeThe file contains 2474 lines, each corresponding to an individual in the study. Columns contain in turn: the individual's identification, (column 1) family (column 2), three measured traits : weight, length and CF (column 3,4 and 5 respectively), type: farm hybrid or wild (column 6), parents (column 7 and 8). The following columns are the SNP genotypes coded as 0101 0102 0201 or 0202.data_summary.txt ... |
