A researcher is interested in screening for p-elements inserted into a region on chromosome 3. to produce new insertions, she crosses females homozygous for a miniwhite + p-element on the x chromosome with males homozygous for immobilized transposase on chromosome 2. what genotype will the f1 male flies have? (note that a "+" indicates a wild-type chromosome without the transposase locus or the p {miniwhite +} insertion. the x /y chromosomes are listed first, followed by the second
