Identification of QTL controlling meat quality traits in an F2 cross between two chicken lines selected for either low or high growth rate

Table 4 Segregation of QTL in each sire family and origin of alleles

			Origin of the dominant allele
Trait¹	Chr	Heterozygous sire families	HG line	LG line
BCo-Y	1	1-3-4	1	3-4
DL	1	1-2-3-4-5	-	1-2-3-4-5
pH15	1	5	5	-
pH15	2	1-2-3-4-5	1-4	2-3-5
pHu	4	1-2-3-4	2-3-4	1
BCo-Y	11	2-3-4-5	-	2-3-4-5
BCo-R	11	1-2-3-4-5	1	2-3-4-5
pH15	12	1-2-4	2	1,4

¹BCo-Y = yellowness; DL = drip loss; pH15 = pH 15 minutes post-mortem; pHu = ultimate pH; BCo-R = redness.
