A researcher has a laboratory strain of flies that have loss-of-function mutations in both gene X and white. These flies are used as hosts for P element transformation: Embryos of the double mutant strain are injected with two plasmids, one containing a wild-type copy of the white gene (w ) and a wild-type copy of gene X, side-by-side within P element inverted repeats, and the other plasmid containing only the P element transposase gene. Transgenic offspring of the injected flies will A. have red eyes and a wild-type copy of gene X in place of the mutant copy in their genome. B. have white eyes and express transposase. C. have both plasmids integrated randomly into the genome. D. have red eyes and a wild-type copy of gene X integrated into a random location in the genome.
