Fig. 3From: Evaluation of the mechanisms of intron loss and gain in the social amoebae Dictyostelium The probability distributions of the loss of adjacent intron pairs in Dictyostelium discoideum. The X-axis represents the pairs of adjacent intron losses, and the Y-axis represents their probability of appearance when each intron is lost independently. The observed pattern, 16 pairs of adjacent intron loss, has a very low probability of occurrence via the independent loss of each intronBack to article page
