Out of 200 individuals originally sent for sequencing, 14 samples did not pass the quality control and were therefore not sequenced, resulting in a total of 186 sequenced individuals. Quality filtering after variant discovery resulted in a dataset of 1 205 604 SNPs. During dissections, some samples were broken resulting in slightly different sample sizes for each trait; total length: N = 186, gut length: N = 106, plate number: N = 160, DS1 and DS2: N = 159, PS: N = 158, GRN: N = 133, GRW: N = 159, GRL2 and GRL3: N = 159.
