Does Frequency-Dependent Selection with Complex Dominance Interactions Accurately Predict Allelic Frequencies at the Self-Incompatibility Locus in Arabidopsis halleri? (2008)

Violane Llaurens, Sylvain Billiard, Jean-Baptiste Leducq, Vincent Castric, Etienne Karl Klein, Xavier Vekemans

Frequency-dependent selection is a major force determining the evolutionary dynamics of alleles at the self-incompatibility locus (S-locus) in flowering plants. We introduce a general method using...

Maintenance of handedness polymorphism in humans: A frequency-dependent selection model (2007)

Billiard, Sylvain, Faurie, Charlotte, Raymond, Michel

Frequency-dependent selection is an important process in the maintenance of genetic variation in fitness. In humans, it has been proposed that the polymorphism of handedness is maintained by negative...

Frequency-dependent selection is an important process in the maintenance of genetic variation in fitness. In humans, it has been proposed that the polymorphism of handedness is maintained by negative...

EVOLUTION OF MIGRATION UNDER KIN SELECTION AND LOCAL ADAPTATION (2005)

Sylvain Billiard, Thomas Lenormand

We present here a stochastic two-locus, two-habitat model for the evolution of migration with local adaptation and kin selection. One locus determines the migration rate while the other causes local...

A General Model to Explore Complex Dominance Patterns in Plant Sporophytic Self-Incompatibility Systems

Billiard, Sylvain, Castric, Vincent, Vekemans, Xavier

We developed a general model of sporophytic self-incompatibility under negative frequency-dependent selection allowing complex patterns of dominance among alleles. We used this model...
