Figure 2

A shifted PAR boundary in M. m. castaneusCAST. The PAR boundary of M. m. castaneusCAST is located approximately 430 kb upstream of the boundary in the reference mouse genome (C57BL/6J). The red bar denotes regions of X and Y chromosome homology. Black vertical bars denote the 10 exons of Mid1, which span the boundary in C57BL/6J (intron sizes are not drawn to scale between the two subspecies). The PAR boundary in M. m. castaneus is proximal to the Mid1 transcription start site. The centromere (cen.) and telomere (tel.) ends of the X chromosome are indicated.
