The project aim to understand the relationship between different loci involved in a complex genetic trait.
To do so, the project use the genomes of 4000 chickens (.4x to 30x) from a cross between two lineage.
The first goal is to improve our linkage map of the chicken genomes using the data from an intercross with 60 founders and 90 F1.
In a second time to look at the relationship between the loci involved in the control of the weight. This part of the project imply to develop new methods to impute the genotypes using Illumina sequencing at low coverage associated with haplotypes infered during the first part of the projects.
