Abstract

Labyrinth fishes of the families Anabantidae, Belontiidae,Helostomatidae, and Osphronemidae comprise the tradi-tional anabantoids, a group of about 80 relatively small African and southeast Asian species (Linke 1991). Many of the anabantoids are popular with aquarium hobbyists because of their interesting reproductive behaviours, with males of most species brooding eggs in their mouths or in floating bubble nests (Vevers 1980; Linke 1991; Axelrod and Vorderwinkler 1995; Mills 2000). They have also beenthe focus of several environmental, morphological, and gene-tic investigations (Sommer 1982; Gosline 1985; Waki-yama et al. 1997; Frankel 1992, 2001). The two-spot gourami, Trichogaster trichopterus trichopterus Pallas (Osphronemidae), is one of the more popular labyrinth fishes due to its peaceful nature and attractive appearance of gold spotting on its dorsal and anal fins. Digenic control of colouration in the two-spot gourami Trichogaster trichopterus trichopterus. As a part of ongoing work on the inheritance of colouration and banding patterns of teleostean fishes (Frankel 1992, 1997, 1998, 2001, 2002, 2004), studies on the mode of inheritance of the colour variants in the two-spot gourami were undertaken, and are reported here.
