Depletion of gene ontology (GO) categories in genes without long introns. Depletion probabilities for gene sets with short exons only calculated by the hypergeometric distribution. Genes were ordered by the minimum teleost length of their longest introns and the probability of observing the observed, or fewer, number of members of the indicated GO categories calculated for all nested sub-sets. Analyses were calculated separately for A) biological process (BP), B) molecular function (MF) and C) cellular compartment (CC). The probabilites (y-axis, -log₁₀p) are shown plotted against the size (log₂ transformed) of the largest intron of the nested set (x-axis)
