description

A modal diploid number 2n=38 has been determined in both sexes of the pleuronectiform Bothus podas from the Gulf of Palermo (Mediterranean). An XX-XY sex-determining mechanism presumably occurs in this species. Application of silver staining (NORs) along with G- and C-banding techniques showed that secondary constrictions occurring in a large metacentric pair were variable in length in different fish. Polymorphisms of these areas seem to have a genetic, rather than transcriptional, basis.
