Structural allelism of six mutants of the ml-o locus was studied by Jorgensen and Jensen (1). They report evidence for three sites within the ml-o locus and the possibility that the mutants might be functionally different.
Seip and Tsuchiya (2) located the ovaryless mutant ovl on chromosome 4 by trisomic analysis.
