Tac chromosome paints hybridized to male Oan metaphases. (a) Paint Tac X₁ (red) hybridized to Oan X₁ and Oan Y₁q. Paint Tac X₂ (green) hybridized to Oan X₂ and the pairing region on Oan Y₂ and Y₁p (arrow head). (b) Paint Tac Y₂ covers Oan Y₂ and hybridized to Oan X₂ and Oan X₃. (c) Paint Tac X₃ hybridized to Oan X₃ and the pairing region on Oan Y₂, the two additional signals are centromeric heterochromatin. (d) Tac paint X₅ hybridized to Oan 12p. (e) Paint Tac Y₄ (red) hybridizes to Oan 12p, and to Oan X₅p and Oan Y₄p. Paint Tac 27 identified Oan Y₃, Oan X₄, and Oan Y₄q. (f) Paint Tac X₄ covers Oan X₅.
