Speciation genes in native New Zealand leafroller moths
… loci are characterized by the absence of ancestral polymorphism and diminished or no gene ow. This work investigates whether Pheromone Binding Protein 1 (PBP1) fulls the criteria of a speciation gene in a complex of native New Zealand Leafroller moths. Ctenopseustis and Planotortrix …

A test of the Snowball model
… I show that recombination rate, gene flow, and ancestral polymorphism can slow down the snowballing of incompatibilities between diverging populations. These factors result in selection for mutationally robust genotypes, and genotypes that are more resistant to mutations are also more resistant …

Genetic variation in fast-evolving East African cichlid fishes: an evolutionary perspective
… a sample genotyping study found that biallelic polymorphisms segregate widely throughout the Malawi species flock, making each species a mosaic of ancestrally polymorphic genomes. A second genotyping study expanded our evolutionary analysis to cover the entire East African cichlid radiation, …

Studio molecolare dei meccanismi dell'autoincompatibilità gametofitica in pero europeo (Pyrus communis)
… to highly conserved RNases, suggest a shared ancestral polymorphism also for the F-box genes. The F-box genes identified in European pear were mapped on a segregating population of 91 individuals from the cross 'Abbé Fétel' × 'Max Red Bartlett'. All the genes were placed on the linkage group …
