How chromosomal inversions reorient the evolutionary process
Berdan, Emma L.; Barton, Nicholas H.; Butlin, Roger; Charlesworth, Brian; Faria, Rui; De mendonça fragata almeida, Inês; Gilbert, Kimberly J.; Jay, PaulInversions are structural mutations that reverse the sequence of a chromosome segment and reduce the effective rate of recombination in the heterozygous state. They play a major role in adaptation, as well as in other evolutionary processes such as speciation. Although inversions have been studied since the 1920s, they remain difficult to investigate because the reduced recombination conferred by them strengthe...
Hybridization patterns between two marine snails, Littorina fabalis and L. obtu...
Costa, Diana; Sotelo, Graciela; Kaliontzopoulou, Antigoni; Carvalho, João; Butlin, Roger; Hollander, Johan; Faria, RuiCharacterizing the patterns of hybridization between closely related species is crucial to understand the role of gene flow in speciation. In particular, systems comprising multiple contacts between sister species offer an outstanding opportunity to investigate how reproductive isolation varies with environmental conditions, demography and geographic contexts of divergence. The flat periwinkles, Littorina obtus...
