Example FISH Results. BAC WAG13K4 on A) chicken (Gallus gallus; GGA) chromosome 1p and B) duck (Anas platyrhynchos; APL) chromosome 1q. BAC WAG13I5 on C) chicken chromosome 4q and D) duck chromosome 4 demonstrating part of the evidence that led us to deduce a paracentric inversion. Conserved synteny among the microchromosomes was tested by dual color FISH. An example is shown for E) GGA15 and F) APL16 using BACs WAG10L1 and WAG93I1. Scale bars represent five microns.
