The abnormal mutation rate in the past population studies of pigs

A. The pig mutation rate was inferred using MSMC2 when fixing the divergence time between SCWs and EUWs at 1.2 MYA. SCW–EUW divergence time was inferred by MSMC2 using various mutation rates with 3 years fixed as the generation interval. Dots, lower bars, and upper bars represent the time at which cross-coalescence rate dropped below 50%, 25%, and 75%, respectively. The red horizontal line represents the SCW–EUW divergence time from Frantz and colleagues [3]. B. Scatter plot showing the mutation rates of pigs (triangles) estimated in our study and used in the past research, with the mutation rates of other species (circles) shown in Figure 1.
