Table 2 Cooperative expression regulation of 175 mapped genes

	cis-acting	trans-acting	total
primary eQTL	395	107	502
secondary cis-eQTL per primary eQTL	n	33
secondary trans-eQTL per primary eQTL	395	74
tertiary trans-eQTL per primary eQTL	8	2
Total verifiable peaks identified	428	586	1014

The strongest eQTL identified regulating the expression of any particular gene is considered the primary identified eQTL. Up to two additional, yet weaker, functional expression regulators were identified regulating the same gene and are considered secondary or tertiary eQTL. Total verifiable cis-acting eQTL identified = 428 (bold); total verifiable trans-acting eQTL identified = 586 (italics). Due to the resolution of the genetic map, only one cis-acting eQTL can be identified per gene being measured, n = not possible.
