TABLE 2.

Summary of significant SNP genotype frequencies (linear regression GWAS, recessive) in Katahdin study population. The majority of animals examined (n = 582) had either entirely homozygous alternate, entirely homozygous reference or entirely heterozygous genotypes at the four significant SNPs. One animal is not represented in the genotype frequency table as it possessed homozygous alternate genotypes with the exception of a single heterozygous genotype at SNP rs417983470. A further eight animals had missing genotypes inferred in order to be placed into allele distributions.
