Fluorescent in situ hybridisation to P. dumerilii chromosomes. The left-hand panel shows signals of Pdu-Gsx and Pdu-Xlox (CHORI305_76L3) (red) and Pdu-Cdx (CHORI305_108J4) (green) on a typical interphase nucleus, showing that the red and green signals are consistently in similar regions of the nucleus, but with a relatively large distance between them. This is consistent with results on metaphase chromosomes (right-hand panels), in which signals of Pdu-Gsx (CHORI305_233N17) (red) are located near to the centromere of a q arm, and Pdu-Cdx (CHORI305_108J4) (green) on the telomeric end on the same chromosome. (Bars = 20 μm).
