Transcription of B-linked genes in Astyanax species. a Gene expression profile of the B chromosomes of A. scabripinnis (Asc) and A. paranae (Apa) in gonadal and somatic tissues. Note that most B-linked transcripts belong to the nobox gene in the ovary. b Gardner-Altman estimation plots showing nobox transcription level in 0B and 1B individuals, analyzed by RT-qPCR. Both groups are plotted on the left axes, and the mean difference (effect size) is plotted on a floating axis on the right as a bootstrap sampling distribution. The mean difference is depicted as a black dot, and the 95% confidence interval is indicated by the ends of the vertical error bar. Note that (i) effect size was almost 5-fold higher in B-carrying (1B) than B-lacking (0B) ovaries of A. scabripinnis and A. paranae, (ii) that it was one order of magnitude lower in muscle, and (iii) that there was no difference in testes (here displayed only for A. scabripinnis). NREQ = normalized relative expression quantity. Asc = A. scabripinnis. Apa = A. paranae
