An attempt to measure the extent of the variation for null-activity alleles at the Esterase-6 (Est-6) locus in Drosophila melanogaster is reported. In the method a laboratory stock was used carrying a third chromosome with an Est-6 O allele, balanced with an Est-6 S -ultrabithorax (Ubx) chromosome. The results suggest that Est-6 null alleles are present at polymorphic frequency in some Italian populations.
