And the exon intron junctions, the length of introns, and the numbers of intron insertions within coding regions were inferred, and listed in Additional file [see Additional file ]. Figure and represents the histograms of intron insertion numbers within coding regions for two major groups of vertebrate GNBs, that is, GNB 1 to 4 and GNB 5 groups, respectively. Anamniotic vertebrates mean fish and amphibian, and amniotic birds and mammals. Abscissa, Intron numbers. Ordinate, and Number of genes, which showed the numbers of intron insertions in the coding regions as indicated on the abscissa. Figure C and D is the similar histogram for two major groups of GNBs genes of the protostomic clades, that is, and , and and . Extra means Gbeta76C genes of and
