Figure 4

Selective sweeps in maize Meg gene region identified by composite-likelihood analysis. We used a spatially-explicit likelihood model to identify recent selective sweeps within the region of maize chromosome 7S containing the Meg gene array from polymorphism data (see Methods). We plot the log-likelihood support in favor of a selective sweep model along chromosome position. A dotted horizontal line indicates the empirically-derived 0.05 significance cutoff, with log-likelihood greater than the dotted line indicating significant support for a selective sweep. (A) We plot support for a selective sweep across the 30-Mb region of chromosome 7S containing the Meg gene region. (B) Close-up of the chromosomal region containing the Meg gene cluster, with each Meg gene’s coding sequence indicated.
