LD4X : un logiciel informatique pour tester le déséquilibre de liaison entre marqueurs chez des espèces autotétraploïdes

Abstract : Autotetraploidy is frequent in forage species (Medicago sativa, Dactylis glomerata, Lotus corniculatus…) and other crops. LD4X program performs a Fisher exact test between pairs of alleles at two loci. For each pair of alleles, a contingency 5x5 table with the allelic dosage from 0 to 4 for each allele is built. Then a Fisher exact test is performed to test a departure from equilibrium between these two alleles, giving the probability of significance of the F test. All combinations of alleles from two loci are treated in turn. If two alleles of a pair of loci have a non-random distribution, the markers are considered as linked.
