Figure 2From: Comparative BAC-based mapping in the white-throated sparrow, a novel behavioral genomics model, using interspecies overgo hybridizationImage of a sparrow BAC filter hybridized to a set of 36 overgo probes. The probes were mostly derived from the chicken sequence. The filter has six panels, with gray double spots of anchor probes shown at panel intersections and utilized for filter grid alignment at the computer image analysis stage. Other black and gray double spots represent hybridization signals.Back to article page
