  • Cho, Kelly; Yang, Qiong; Dupuis, Josée (BioMed Central, 2007-12-18)
    The presence of linkage disequilibrium violates the underlying assumption of linkage equilibrium in most traditional multipoint linkage approaches. Studies have shown that such violation leads to bias in qualitative trait ...
