Amplification of int1h-1 and int1h-2 regions.

Regions were amplified using 9F, 9cR, and Int1h-2F primers (lanes 1,2), and int1-2F, int1h-2R, and 9F primers (lanes 3,4). Lanes 1 and 3 show a male with inversion; lanes 2 and 4 show a wild-type male. MVI indicates DNA molecular weight marker VI (Boehringer Mannheim, Mannheim, Germany). The dimensions of the amplified fragments are approximately 1500 bp and 1000 bp.
