X-linked and autosomal inheritance patterns of homologous genes in two species ofTribolium

The tenebrionid beetlesTribolium castaneum andT. confusum are representative of two distinct species groups within their genus. It has been suggested [Smith, S. G. (1952).J. Morphol.91:325] that the 8AA + neo-XY karyotype ofT. confusum was derived from the ancestral 9AA + XY formula, still present inT. castaneum, via the fusion of one pair of autosomes with the X and Y chromosomes during the early divergence of theconfusum and castaneum species groups. In the present paper, electrophoretic variation in malic enzyme and hexokinase-1, detected in laboratory strains inTribolium, is described. Evidence is presented that the genes encoding variation in both enzymes are autosomal inT. castaneum but are X linked inT. confusum. These species-specific patterns of inheritance of homologous gene loci are consistent with the hypothesized karyotypic history of the genus.
