compilation of phenotypic differences between species of the D. melanogaster subgroup

et Marie Curie, Paris, France
The D. melanogaster subgroup comprises nine species: D. melanogaster,
D. simulans, D. sechellia, D. mauritiana, D. yakuba, D. santomea, D.
teissieri, D. erecta and
subgroup is currently one of the best model system to study the genetic
and genomic basis of evolution (phenotypic evolution, speciation,
genomic conflict, phylogeography, etc.):
(1) most of these species'
genomes are sequenced,
(2) multiple technical tools
such as transgenesis are available,
(3) most of these species are
recently diverged and can still produce hybrids in the laboratory,
(4) the nine species have
evolved to exploit a wide diversity of ecological niches.
these nine species are morphorlogically very similar, more than 150
interspecific phenotypic differences (morphological, physiological or
behavioral) have been reported in the literature since 1919. This web
page is intended to synthesize
all these studies. For any two species of the D. melanogaster subgroup which can produce
hybrids, you can obtain here a list of the phenotypic traits that
between them, with links to the corresponding references.
