Deletion of the C-terminal portion of prd.
Two copies of prdN fail to rescue the cuticle phenotype of prd4 homozygous embryos. Two copies of prdN fail to rescue prd4/Df(2L)Prl animals to adulthood. Two copies of prdN fail to rescue the fertility of prd4/Df(2L)Prl males (in a background where prd4/Df(2L)Prl viability has been rescued by two copies of gsb::prdGsbN+PrdC).
