organism

Wanderings , a transposon in , and its close relatives,ies. The full-size . and . elements are 99.9% identical at the DNA sequence level, and internally deleted copies in these species essentially differ only in having deletions. In addition to these, .-related sequences are present and detectable with a . probe in all these species. Those in . are 86-9

Mitotic and polytene chromosomes: comparisons between , and ,, is mainly based on the methods that allow to differentiate their euchromatin from their heterochromatin: banding patterns, distribution of satellite DNAs and location of the rDNA. The polytene chromosomes karyotypes are known for many years to differ by a major paracentric inversion on chromosome 3

RACE

Comparative analysis of morphological traits among , and ,: genetic variability, clines and phenotys, which are often arranged in latitudinal clines. Such clines are documented for body weight, wing and thorax length, sternopleural and abdominal bristle number, ovariole number and thoracic pigmentation. The overall magnitude of geographical differentiation is, however, much less in . than in ., a

Relations between cuticular hydrocarbon (HC) polymorphism, resistance against desiccation and breed (7T) as the major compound type [7T]s and [7T]m, or 7-pentacosene (7P) [7P]s and [7P]m. . females display 7,11-heptacosadiene (7,11HD) as the major compound: [7,1 lHD]m, or 5,9-heptacosadiene (5,9HD) [5,9HD]m. The [7P]s, [7P]m and [5,9HD]m are mainly present in central Africa. A significant correla

A mutation in , that lengthens the circadian period of locomotor activity,ion of the fly circadian clock. In ., balancing selection appears to maintain a polymorphism in this region, with three repeat lengths carrying 23, 24 or 25 Thr-Gly pairs, each in complete linkage disequilibrium with a distinctive flanking region amino acid moiety. We wondered whether separating a s

Sperm size evolution in ,: inter- and intraspecific analysis,iations of sperm size are very scarce and the number of sperm measured, very limited. This paper investigates within-individual, between-individual and between-population variation of sperm length in the two cosmopolitan species, . and .. Sperm length distributions are completely discriminated again
