Fig. 4From: Expansion of the HSFY gene family in pig lineagesFISH using HSFY-containing fosmids. (a) Multi colour FISH using HSFY-containing Sus scrofa WTSI_1061 Y-fosmid clones 50E19, 57Â F7, 69Â M14, 70O20 on Sus scrofa metaphases. Each clone is labelled with a different colour, and co-localising probes show a white signal. All the clones hybridise to the same region of the short arm of the Y chromosome (expanded in box), concordant with cytogenetic band Yp1.2. (b) Fibre-FISH using fosmid clone 25O19. The single 40Â kb clone hybridises across the ~500Â kb region within the figure. Note that the hybridisation pattern is not continuous - there are other as-yet-unidentified amplified sequences within the HSFY regionBack to article page
