We investigated the distribution of PRE-1 sequences (a swine major SINE) on the swine chromosomes. The investigation demonstrated that PRE-1 sequences are unevenly distributed along the chromosomes as in the case of the human and mouse SINES. The distribution pattern, however, has no simple correlation with Q-band pattern as that of human and mouse SINES. The prominent difference is as follows; PRE-1 is localized on centromeric regions, but human and mouse SINES are not [KORENBERG and RYKOWSKI (1988). Cell, 53: 391-400; BOYLE, BALLARD, and WARD(1990).
