Data for "No pedigree, no problem: genomic inbreeding tracks genetic rescue with high resolution"

This data support the Evolutionary Applications article “No pedigree, no problem: genomic inbreeding tracks genetic rescue with high resolution.” The study examines how genetic rescue influences inbreeding estimates derived from pedigree and genomic data.
The dataset comes from a long-term study of Rocky Mountain bighorn sheep (Ovis canadensis) at Ram Mountain, Alberta, Canada. Following a population decline, 35 sheep were translocated to the population between 2002 and 2015 to reduce inbreeding.
Pedigree inbreeding coefficients were calculated using the standard recursive tabular algorithm based on the additive relationship matrix. Genomic inbreeding coefficients were estimated from runs of homozygosity detected with a Hidden Markov Model using SNP genotypes from a custom 50K panel.
Genomic inbreeding decreased following genetic rescue, whereas pedigree inbreeding increased across cohorts, likely reflecting increased pedigree depth in later years.
