Even so, in females from two broods with fragmented sex chromatin, only part of the W chromosome was labeled with the Wpainting probe, and telomeric Cyclohexanecarboxylic acid manufacturer signals had been detected at both ends of this large W chromosome too as painting probe, and telomeric signals were detected at each ends of this big W chromoat both ends of its two pairing partners, Z1 and Z2 (Figure 3r,s).
