Transcript levels of genes encoding putative gamete-enriched proteins.

<p>Transcript levels of six genes encoding putative gamete-enriched proteins and of glyceraldehyde 3-phosphate dehydrogenase (GAPDH) in somatic tissues and gametes were monitored by quantitative PCR and normalized to ubiquitin mRNA. The data are means ±SE of two independent experiments. The numbers at the bars indicate values of relative mRNA levels.
