Total, the total number of scored males; Nu, the total number of males with a transposon insertion at an autosome; Q, the average frequency of transposition. The probability value (P) was determined with a 2 × 2 contingency test (the Statistica 6.0 program, StatSoft, 1984–2001) comparing frequencies of P transposition on the mod(mdg4)+ and mod(mdg4)u1 backgrounds.
