Acoustic signals often play a significant role in pair formation and in
species recognition. Determining the genetic basis of signal divergence
will help to understand signal evolution by sexual selection and its role
in the speciation process. An earlier study investigated QTL for male
courtship song carrier frequency in Drosophila montana using
microsatellite markers. We refined this study by adding to the linkage map
markers for ten candidate genes known to affect song production in D.
melanogaster. We also extended the analyses to additional song characters
(pulse train length, pulse number, interpulse interval, pulse length and
cycle number). Our results indicate that loci in two different regions of
the genome control distinct features of the courtship song. Pulse train
traits (pulse train length and pulse number) mapped to the X chromosome,
showing significant linkage with the period gene. In contrast, characters
related to song pulse properties (pulse length, cycle number and carrier
frequency) mapped to the region of chromosome 2 near the candidate gene
fruitless, identifying these genes as suitable loci for further
investigations. In previous studies, the pulse train traits have been
found to vary substantially between Drosophila species, and so are
potential species recognition signals, while the pulse traits may be more
important in intra-specific mate choice.
Song_dataThis dataset contains measurements of song traits (means from 3
measurements per individual) for 3 generations of experimental
crosses.QTL_dataThis dataset contains information on song traits and
genotypes at microsatellite and candidate gene markers for males from F3
generation of experimental crossess.
