this enhancer of segregation distortion [ e ( sd ) ] locus had not been characterized in earlier studies of sd chromosomes because it can not be readily separated by recombination from the responder ( rsp ) locus in the proximal heterochromatin of 2r. -- to determine whether e ( sd ) is a general component of all sd chromosomes and to examine further its effects on distortion , we produced deletions of e ( sd ) in three additional sd chromosomes .
