Fig. 4.

Higher coefficients of inbreeding (F) are equally likely in breeds that are longer-lived or shorter-lived than expected based on their size. Life expectancy is plotted against log₁₀(male average weight) for 105 breeds for which inbreeding estimates are also available. Trend line shows expected life expectancy based on regression on size only. Points are colored by breed-average level of inbreeding, such that outbred breeds are black and inbred breeds are red. Regression coefficients from regression of log₁₀(male average weight) and coefficient of inbreeding (F) on adjusted life expectancy are given. Breed abbreviations are given in Table S4 (ESM2)
