Data for: Genomic insights into inbreeding and adaptive divergence of trout populations to inform genetic rescue

Genetic rescue, specifically translocation to facilitate gene flow among populations and reduce the effects of inbreeding, is an increasingly used approach in conservation. However, this approach comes with tradeoffs, wherein gene flow may reduce fitness when populations have adaptive differentiation (i.e., outbreeding depression). A better understanding of the interaction between isolation, inbreeding, and adaptive divergence in key traits, such as life history traits, will help to inform genetic rescue efforts. Stream dwelling salmonids, such as the westslope cutthroat trout (Oncorhynchus lewisi;WCT), are well-suited for examining these tradeoffs because they are increasingly isolated by habitat degradation, exhibit substantial variation in life history traits among populations, and include many species of conservation concern. However, few genomic studies have examined the potential tradeoffs in inbreeding versus outbreeding depression in salmonids.

## Description of the data and file structure

Genetic samples of westslope cutthroat trout were collected during random sampling of 25 populations. Genotypes were generated using BestRAD protocol. 

#### File: belletal\_genotypes.txt

**Description:** Sample_id provides unique IDs for all individuals used in the final analyses. The remaining columns are 0, 1, 2 format genotypes with column names corresponding to the position on a rainbow trout reference genome (NCBI OmykA_1.1).
