Fig. 5.

Fold change distribution of the expression of macaque sperm genes in the testis as compared with the average expression in other tissues. The majority of genes are between twofold under- and overexpressed whereas a small subset show significant under or overexpression. Blue color indicates number of genes also found in the set of 242 unique genes whose testis expression is significantly different from expression in all other tissues. Inset: Comparison of the 242 statistically significant MacSP genes (blue) to all other MacSP genes as a proportion of the total.
