Internal deletion of the P-element, 20bp remains at the 5' end. Also sequence alterations in the 8bp flanking duplications.
One of the "whd-F" group of alleles (P Fragment template). wB2.1 can be used as a template to convert the whd80k17 P-element sequences with its derivative wB2.1 sequence in the presence of transposase.
