RAD 1	12	12	9.7 × 10⁶	435,006	4,777	9.6 × 10⁻⁶	LG13, UNK25, UNK107
RAD 2	9	8	5.9 × 10⁶	341,384	4,268	1.4 × 10⁻³	LG5, LG14

Families with number of male (M) and female (F) offspring. ^aAverage reads and stacks per offspring. ^bTotal number of polymorphic stacks used for association mapping, requiring a minimum stack depth of 10 to call homozygotes, and genotypes called for 20 of 24 offspring for RAD 1, and 15 of 17 offspring for RAD 2. ^cThe lowest p-value obtained for Fisher’s exact test of allele association with sex, shared by multiple markers (Additional file 3). ^dLinkage groups with markers with lowest p-value association
