New gene distribution on the chromosomes and upregulation of expression in testis. a Distribution of duplication/retroposition genes and orphan genes on chromosomes in Monopterus albus.b Line plots showing average expression levels (RPKM) of duplication/retroposition genes and their parental genes during gonad differentiation. P values in the Mann–Whitney U test were calculated for expression level comparisons of new genes among different tissues, and between new genes and parental genes within a tissue. c Box plots showing the expression levels (RPKM) of all new genes and orphan genes, in comparison with all other genes during gonad differentiation (Mann–Whitney U test, *p < 0.05, **p < 0.01; ***p < 0.001)
