Populationwide Investigation of Two Indel Polymorphisms at the Prion Protein Gene in Polish Holstein–Friesian Cattle

The allele, genotype, and haplotype frequencies among 837 Polish Holstein–Friesian cattle were determined at two regulatory indel polymorphisms of the PRNP gene. Allele frequencies at the 23 bp indel promoter polymorphism were 0.622 (del) and 0.378 (ins), with 0.613 and 0.387 in sires and 0.633 and...
