Polimorfisme nucleotídic i canvis adaptatius recents (2009)
En observar els individus d'una espècie es detecten característiques que els fan estar especialment adaptats al medi biòtic i abiòtic en què es troben. La selecció natural és la força motriu...

The FAH1 and F3H genes encode ferulate-5-hydroxylase and flavanone-3-hydroxylase, which are enzymes in the pathways leading to the synthesis of sinapic acid esters and flavonoids, respectively....
Excess Polymorphism at the Adh Locus in DROSOPHILA MELANOGASTER
Kreitman, Martin E., Aguadé, Montserrat
The evolutionary history of a region of DNA encompassing the Adh locus is studied by comparing patterns of variation in Drosophila melanogaster and its sibling species, D. simulans. An unexpectedly...
A Test of Neutral Molecular Evolution Based on Nucleotide Data
Hudson, Richard R., Kreitman, Martin, Aguadé, Montserrat
The neutral theory of molecular evolution predicts that regions of the genome that evolve at high rates, as revealed by interspecific DNA sequence comparisons, will also exhibit high levels of...

The adaptive character of inversion polymorphism in Drosophila subobscura is well established. The OST and O3+4 chromosomal arrangements of this species differ by two overlapping inversions that...
Braverman, John M., Lazzaro, Brian P., Aguadé, Montserrat, Langley, Charles H.
Several evolutionary models of linked selection (e.g., genetic hitchhiking, background selection, and random environment) predict a reduction in polymorphism relative to divergence in genomic regions...
Large-scale adaptive hitchhiking upon high recombination in Drosophila simulans.
Quesada, Humberto, Ramírez, Ursula E M, Rozas, Julio, Aguadé, Montserrat
Natural selection is expected to leave a characteristic footprint on neighboring nucleotide variation through the effects of genetic linkage. The size of the region affected is proportional to the...
