Probabilistic reconstruction of genealogies for polyploid plant species.

In this talk, I will present a probabilistic method in order to reconstruct genealogies in a polyploid population, by considering genetic data analyzed as the probability of allele presence in a given genotype.
In particular, we compute the likelihood associated with all crossbreeding patterns and I will explain how to build and quantify the whole potential genealogies of the population and how to treat the unknown allelic multiplicity.
Then we treats the isolated individuals, under some criteria we suggest an algorithm computing virtual individuals to improve the genealogy.
All the results will be tested both on a simulated population and a rose bushes population.

Ce travail est fait en collaboration avec F. Proïa, F. Panloup et J. Clotault de LAREMA Angers.
