Comparisons of the allele frequencies of PRNP codons 143, 146, 168, 211, and 222 in Greek, French and Korean goats. (A) Comparisons of the allele frequency of the PRNP codon 143 between Greek goats and Korean native black goats³. (B) Comparisons of the allele frequency of PRNP codon 146 between Greek goats and Korean native black goats⁵⁰. (C) Comparisons of the allele frequency of the PRNP codon 154 between French goats and Korean native black goats⁵⁸. (D) Comparisons of the allele frequency of PRNP codon 168 between Greek goats and Korean native black goats⁵⁰. (E) Comparisons of the allele frequency of PRNP codon 211 between French goats and Korean native black goats³³. (F) Comparisons of the allele frequency of PRNP codon 222 among French goats, Greek goats and Korean native black goats^33,41. Differences in allele distributions were calculated by chi-squired (χ²) tests and Fisher’s exact test. S: scrapie-affected goats, C: healthy goats.
