Average genome-wide inbreeding (left) and kinship (right) by year of birth. Coefficients of IBD (\(F_{PED}\), \(F_{ROH}\), \(f_{PED}\), \(f_{SEG}\)) and IBS (\(HOM_{SNP}\), \(SIM_{SNP}\)) are shown on the primary and secondary y-axis, respectively. \(F_{PED}\) and \(f_{PED}\): genealogical inbreeding and kinship; \(F_{ROH}\) and \(f_{SEG}\): segment-based inbreeding and kinship;\(HOM_{SNP}\) and \(SIM_{SNP}\): marker-by-marker homozygosity and similarity
