Table 2. Allelic states observed in each GWAS model, resulting from a combination of SNP alleles, their ancestry and the genetic background in which they are observed.

	SNP	Ancestry	Genetic background	Allelic states
M1	{0, 1}	-	-	{0, 1}
M2	{0, 1}	{D, F}a	-	{0D, 1D, 0F, 1F}
M3	{0, 1}	{D, F}	{D, A, F}	{0DD, 1DD, 0DA, 1DA, 0FA, 1FA, 0FF, 1FF}

0: SNP reference allele

1: SNP alternative allele

D: Dent ancestry or genetic background

F: Flint ancestry or genetic background

A: Admixed genetic background

^a confounded with the genetic background
