Table 2 legend: Summary of likelihood ratio statistics (2LLR), degrees of freedom (df) and significance level (P-value) when comparing the full likelihood model (ABCDE) to four different nested models (ABC0D (m1 = 0), ABCD0 (m2 = 0), ABC00 (m1 = m2 = 0), ABCDD (m1 = m2 > 0)), using IMa for autosomal and Z-linked loci, respectively.
