Relaxed silencing of the X chromosome reflected by a high X:autosome transcription ratio in sterile B10-T43/+ males. The X-to-autosome transcription ratios are shown for individual cell populations and mouse genotypes. For each genotype, the mean ratios of two independently isolated populations are displayed together with their range. BT, B, and T stand for B10-T43/+, B10, and B10-T43H/T43H genotypes, respectively.
