Between-species comparison of D.melanogaster and C.elegans developmental stages from different aspects. The mapping scores shown on the correspondence map are − log₁₀ (p-value), which are calculated from the overlap test. a Mapping scores are calculated from the aspect of alternative splicing patterns. i.e., given two stages of fly and worm, the statistic is the number of conserved exon pairs in the stage-associated exons of the two species. b Mapping scores are calculated from the aspect of gene expression. i.e., we find stage-associated genes for every stage as the genes with high relative expression and distinguishable absolute expression at that stage. Given two stages of fly and worm, the statistic is the number of orthologous gene pairs in the stage-associated genes of the two species. Panel (b) has been adapted from [11]
