Fig. 2: Divergent positive selection on ancestral GM symbiont strains in wild and laboratory mice.
From: Recent genetic drift in the co-diversified gut bacterial symbionts of laboratory mice

Scatter plot shows the log of the dN/dS ratio for bacterial genes in co-diversifying clades in laboratory house mice (y-axis) and wild house mice (x-axis). Each point represents a bacterial gene. Positive values indicate evidence of positive selection, values near zero indicate neutral evolution, and negative values indicate purifying/negative selection. Points in the upper left quadrant show evidence of positive selection in laboratory house mice but purifying/negative selection in other rodents. Source data are provided as a Source Data file.
