Fourth Pair

A new recessive eye color mutant, hazel, of the flour beetle, Tribolium castaneum, has been mapped in linkage group IV near the white locus, thus establishing the existence of a fourth pair of closely linked eye color genes in this species. A revision of linkage group IV is proposed.

Dominant Mutants

Reindeer (Rd) is a dominant mutation affecting antenna morphology in the tenebrionid flour beetle, Tribolium castaneum. In contrast with most dominant mutants previously described for this species, homozygotes are fully viable, thus making Rd very useful for genetic studies. Rd is tentatively assigned to either linkage group IX or X. Abbreviated appendages (aa), formerly placed in linkage group X, is reassigned to linkage group V on the basis of demonstrated linkage to jet (j).Key words: Tribolium, mutation Rd, linkage, antenna morphology.

Dominant Mutant

Reindeer (Rd), an autosomal dominant mutant in the flour beetle, Tribolium castaneum, is located in linkage group IX. Recombination between Rd and alate prothorax occurs more frequently in males than in females. Linkage group IX appears to be the third linkage group for which recombination frequency is greater in males for one region and in females for another region of the chromosome.Key words: Tribolium, linkage.

Number Of Segments

Data are presented to show the linkage relationships of a number of genes in linkage group II of Tribolium castaneum and a revised map of this linkage group is presented bearing eight well-established points. Some of these points were establishable with the aid of an accidental inversion induced by gamma irradiation. Five additional mutants are also in this linkage group as a result of the revision, but their relative position needs to be established through additional linkage studies. The linkage map suggests the presence of two gene clusters, one affecting the eye color and morphology and the other including homeotic mutants that affect the morphology of the maxillary and labial palps, the thorax, and the abdominal sternites. Data are presented to show that the frequency of recombination for a number of segments in linkage group II is not equal in the two sexes. The literature bearing on the evolution of the karyotype in Tribolium is reviewed, and it is concluded, on the basis of the present evidence, that it is linkage group II and not linkage group IX that became translocated to the X and Y chromosome in a T. castaneum like ancestor to produce the much larger neo-X and neo-Y chromosomes of T. confusum. Key words: Tribolium, linkage, gamma irradiation.

Linkage Relationships

A new sex-linked mutation in the flour beetle Tribolium castaneum is described and illustrated. Blob (bb), an antennal mutant, is located near the far right end of the known linkage map of the X chromosome. It is recessive, with incomplete penetrance and variable expressivity, and fails to exhibit dosage compensation. The expression of bb is discussed in relationship to models of antennal development in this species. Apparent rediscovery of the pegleg mutation has confirmed a previous report on the linkage relationships of pearl and pegleg in linkage group II.
