Figure 8From: Incomplete meiotic sex chromosome inactivation in the domestic dogReduced transcriptional activity in the XY body of dog pachytene spermatocytes. Images of Cot1 RNA FISH combined with an immunostaining for γH2AX on spermatocyte nuclei. High γH2AX signals (covering the XY body) correspond to low Cot1 signals, indicating little transcriptional activity. Magnifications of the left and right XY body are shown below each image.Back to article page
