Scenario	Model	${\mathit{\sigma }}_{\mathit{m}}^2$	${\mathit{\sigma }}_{\mathit{f}}^2$	${\mathit{\sigma }}_{\mathit{g}}^2$	${\mathit{\sigma }}_{\mathit{e}}^2$
1	No polygenic or no major X-linked QTL effecta	0	0	0	40
2	No major X-linked QTL effect	0	0	12	28
3	No polygenic effect but major X-linked QTL effect under DC	4	2	0	36
4	No polygenic effect but major X-linked QTL effect under NDC	4	8	0	36
5	Major X-linked QTL effect under DCb,c	4	2	12	24
6	Major X-linked QTL effect under NDCb,c	4	8	12	24

^aMajor X-linked QTL effect means that there is X-linked linkage.

^bAdmixture models with scenarios 5 and 6 for an X-linked single marker have p = r = 0.2 in one subpopulation and p = r = 0.5 in the other subpopulation.

^cAdmixture models with scenarios 5 and 6 for an X-linked haplotype marker have p = 0.2, marker haplotype frequency distribution {0.25, 0.25, 0.25, 0.25} in one subpopulation and p = 0.5, marker haplotype frequency distribution {0.7, 0.1, 0.1, 0.1} in the other subpopulation.
