Conditional expression explains molecular evolution of social genes in a microbe
Genetic diversity in social genes is expected to be shaped by conflict. Here, the authors show that in Dictyostelium discoideum, social genes in fact exhibit diversification patterns consistent with relaxed purifying selection, likely due to their expression only in intermittent social generations.
