Figure 1.

Chromosomal locations of PSR-specific and normal chromosome transcripts obtained from RNA-seq by using DNA fluorescence in situ hybridization. (A−C) Three probes, each corresponding to one of three transcripts (names, respectively) present only in the PSR+ testis, localize specifically to the PSR chromosome (red regions, indicated by red arrows). (D, E) Probes corresponding to two different transcripts present in both control and PSR+ testes highlight single regions on a single normal chromosome.
