Fig. 3. Inbreeding depression in annual survival.

a Distributions of inbreeding coefficients F_ROH in Soay sheep age classes ranging from 0 to 9 years. b Proportion of surviving individuals per year in four different life stages and among different F_ROH classes. As highly inbred individuals are relatively rare, the last class spans a wider range of inbreeding coefficients. Source data for this figure are also provided as a source data file. c Predicted survival probability and 95% credible intervals over the range of inbreeding coefficients F_ROH for each life stage while holding sex and twin constant at 1 (male) and 0 (no twin). The predictions for the later life stages classes exceed the range of the data but are shown across the full range for comparability.
