aOne of the probes selected for GGA16 matches a sequence that has not been assigned yet to a particular chromosome and is designated as 'GGAUn_random' in the chicken genome sequence (Build 2.1).
bGGAW_random is a random sequence known to be located on the W chromosome but is yet to be assembled with the rest of the W chromosome sequence.
