From: Interrogation of alternative splicing events in duplicated genes during evolution

Box plot of protein lengths. Protein length of four groups of genes: A_F, N_F, A_S, and N_S (for AS gene families genes, no AS gene families genes, AS singletons, no AS singletons, respectively) of human across three different identity criteria (>10, >50, >90). When comparing within the same identity and the same duplication status, the length of genes with AS are longer than genes without AS, and this tendency is especially obvious for duplicated genes (gene families) or at lower identity criterion (>10).
