Partitioning of Total Evidence into Three Classes of Genes Based on Parental SNP Differences for the Three Reciprocal Crosses.

Cross type and parameters	Homozygous SNPs only	Heterozygous SNPs only	Both types of SNPs
1. S. peruvianum cross (n genes)	383	5,951	1,895
# candidate MEGs	28	265	58
# candidate PEGs	8	136	28
mat. prop. 1616A	0.649	0.643	0.651
mat. prop. 1616J	0.702	0.682	0.687
2. S. chilense cross (n genes)	278	2,078	204
# candidate MEGs	2	37	1
# candidate PEGs	7	57	6
mat. prop. 4329B	0.642	0.625	0.645
mat. prop. 4329K	0.644	0.639	0.655
3. Hybrid cross (n genes)	995	1,265	1,851
# candidate MEGs	153	160	257
# candidate PEGs	2	4	0
mat. prop. 1616A	0.842	0.845	0.848
mat. prop. 4329B	0.706	0.688	0.708
