Possible insertion of an unidentified mobile element.
Site-specific increase in recombination frequency and premeiotic recombination in males.
This mutation was previously reported to be an allele of Tpl (FBrf0051978). However, the effect on Tpl has been found not to map to the Tpl locus itself at 83E, but instead maps to a separate locus called Su(Tpl) at 76B-76D.
