Fig. 6
Genes on the Y chromosome that have been translocated from the autosomes or genes on the Y chromosome that have been duplicated show testis-biased gene expression. Log2 fold change between testis tissue and three other tissues (brain, larvae, and liver) is shown. The median is indicated by the solid line. Whiskers denote 1.5x the interquartile range. Outliers are not shown. For each tissue comparison, asterisks denote groups with significantly different expression from single-copy genes on the Y chromosome that have an X-linked gametolog (Sex ancestral; Mann-Whitney U test; P < 0.05)
