Patterns of geographic variation of thermal adapted candidate genes in Drosophila subobscura sex chromosome arrangements.

ABSTRACT:

Background

The role of chromosomal arrangements in adaptation is supported by the repeatable clinal variation in inversion frequencies across continents in colonizing species such as Drosophila subobscura. However, there is a lack of knowledge on the genetic variation in genes within inversions, possibly targets of climatic selection, across a geographic latitudinal gradient. In the present study we analysed four candidate loci for thermal adaptation, located close to the breakpoints, in two chromosomal arrangements of the sex (A) chromosome of Drosophila subobscura with different thermal preferences. Individual chromosomes with A₂ (the inverted arrangement considered warm adapted) or A_ST (the standard ancestral arrangement considered cold adapted) were sequen
