Genotype data for: Demographic and genetic consequences of a steelhead supplementation program

# Genotype data for Demographic and genetic consequences of a Steelhead supplementation program [https://doi.org/10.5061/dryad.wstqjq2sx](https://doi.org/10.5061/dryad.wstqjq2sx) Genotypes for 291 single nucleotide polymorphism loci in steelhead captured in Abernathy Creek, WA. The data were used to conduct parentage analysis and infer reproductive success of hatchery- and natural-origin fish spawning in the hatchery and natural environments. ## Description of the data and file structure Genotype data are presented in two-column format (i.e., each allele in its own column), with the locus names indicated in the header row for each column. The Category column indicates how each individual was classified at the time of collection. The Year column indicates spawn year for captive brood individuals, and return year for returning adults. Numeric allele calls are coded as follows: A = 1, C = 2, G = 3, T = 4, deletion = 5, and missing data = 0. ##
