Lethal over parasbl-3 and parasbl-4. parahd2 flies show a normal larval olfactory response to propionic acid at a dilution of 10-1. Transheterozygotes with parasbl-1, parasbl-2, parasbl-5 and parasbl-6 show normal olfactory response to 10-1 propionic acid. Transheterozygotes with parasbl-4, which die as pupae, have wild type levels of olfaction in the larval olfactory assay.
