RECOMBINATION DIFFERENCES WITH RECIPROCAL CROSSES IN TRIBOLIUM CASTANEUM

Genetic modification of recombination rate in Tribolium castaneum.

Asymmetrical responses were obtained in a replicated study of 15 generations of two-way selection for recombination rate between the ruby (rb) and jet (j) loci in Tribolium castaneum. Recombination rates in the two replicate high lines increased from an average of 0.22 in the base populations to an average of 0.42 at generation 15. Recombination rate pooled over the 15 generations of selection ...

Reciprocal Crosses in Streptomyces Coelicolor.

interaction of two complementary growth-factor dependent mutants, i.e., Tzp lemen ta ry auxotrophs, of Streptomyces coeticolor to form grovvth-factor independent progeny, i.e., prototrophs, was interpreted as gene recombination by SERMO~TI and SPADA-SERMONTI (1955) and by BRAENDLE and SZ+BALSKI (1959yi but as heterokaryosis by BRADLEY (1957). The former workers concluded that gene recombination...

Recombination in Species Crosses.

N THE field of mathematics there are numerous problems difficult to I solve with finite numbers which become relatively simple when the concept of infinity is introduced, Similarly, though the genetics of species crosses is obscure when considered in terms of single factors, i t seemed possible that i t might be illuminated if one attempted to consider the total recombination of specific differ...

Embryonic patterning mutants of Tribolium castaneum.

The identification and analysis of genes controlling segmentation in Drosophila melanogaster has opened the way for understanding similarities and differences in mechanisms of segmentation among the insects. Homologues of Drosophila segmentation genes have been cloned and their expression patterns have been analyzed in a variety of insects, revealing that the patterns of expression of many gene...
