Genotype data for CPQ intron-6 SNPs in broiler lines.

The REL, Y and Z lines were genotyped using 5’-exonuclease assay where TA is homozygous reference allele, YM (TA/CC) is heterozygous, and CC is homozygous non-reference allele. Genotype frequencies (Freq) were determined for the entire line (All) or for the ascites resistant (R) or susceptible (S) subpopulations based on phenotype in a hypobaric challenge. Count for All in each line include genotypes from birds with missing gender. The samples were also analyzed by gender. P-values for a simple Bonferroni correction (Adj Pval) of chi square test of observed vs. expected are presented.
