Is Promiscuity Associated with Enhanced Selection on MHC-DQα in Mice (genus Peromyscus)?
Figure 2
Plots of the distribution of selection parameters and statistical tests generated in the program PAML using the 1000 replicate datasets.
Figure 2A is the distribution of omega. Dashed line is the estimate in model 2a, while the solid lines represent the estimate in model 8. 2B, 2C, 2D, 2F are the distributions of the LRT for M1a vs. M2a, M7 vs. M8, branch site tests (PEMA foreground) and branch site test (PECA foreground) respectively. The dashed red line indicates the critical value with df = 2, while the solid red line is placed at omega = 1. Figure 2E and 2G plot the distribution of omega in the branch site test when PEMA or PECA are placed in the foreground position.
