Female-biased coding and non-coding genes are clustered on the X-chromosome. A: Chromosomal locations (NCBI37/mm9 genome assembly) of the known and novel X-encoded female-biased genes presented in Figure 2B. Known coding X-inactivation escapees are marked with "*". B: Higher resolution map, showing that coding and non-coding female-biased genes are proximally paired on the X-chromosome.
