Sex chromosomes and chromosome 14 are enriched in genes expressed after meiosis. a Proportion of round spermatid (RS) enriched genes and round spermatid (RS)-specific genes for the sex chromosomes (X and Y), five representative chromosomes (chromosomes 3, 6, 14, 16 and 18) and all autosomes. The proportion of round spermatid-enriched genes and round spermatid-specific genes is significantly higher for the sex chromosomes and chromosome 14 than for the other autosomes. The level of statistical significance is marked with one asterisk (*) if p < 0.05, two (**) if p<0.01.(*) and three (***) if p<0.001. b RPKM mean values of round spermatid-enriched genes and specific genes for sex chromosomes (X and Y), five representative chromosomes (chromosomes 3, 6, 14, 16 and 18) and all autosomes. Round spermatid-specific genes encoded by the sex chromosomes display significantly lower values than autosomes. The values are indicated in the table. c Distribution of RPKM values of round spermatid-enriched genes and round spermatid-specific genes. The X-axis represents categories of RPKM range of values (0–2, 2–4, 4–6, etc.), and the Y-axis, the percentage of genes in each category. X-linked genes expression values are indicated in pink, Y-linked genes expression values are in green, and autosomal values are in gray. See Additional files 8 and 9 for detailed statistical analyses
