Figure 1.
Presence of putative pseudoautosomal genes in 40,XY (n = 2) and 39,XY*O (n = 2) mice as indexed by PCR from genomic DNA (A); Asmt and Sts genes are deleted in the latter group, whilst the Erdr1 and Mid1 genes (and therefore G530011O06Rik and LOC100861696 genes) are retained. These data indicate that the pseudoautosomal regions of the X and Y chromosomes (B) form an end-to-end fusion at the region between Erdr1 and Sts in 39,XY*O mice (C).
