Abstract

The aim of this study was to assess genetic polymorphism at two loci in the exon 1 of the CSN3 gene in Murgese horse breed by PCR-RFLP analysis. The overall frequencies of alleles A and G at c.-66A >G locus were 0.80 and 0.20, respectively, and no GG animals were found in the population. At the c.-36C > A locus allelic frequencies were 0.74 and 0.26 for allele C and A, respectively, and no AA animals were detected. Population genetic indexes, namely gene heterozygosity, gene homozygosity, effective allele numbers, fixation index, and polymorphism information index were calculated. Combined genotypic frequencies and possible haplotypes frequencies were also reported. Only three out of nine possible genotypic combinations were found in the studied population. The most frequent genotype was AACC (0.49) while the frequency of AGCA was 0.40. Only five animals were genotyped as AACA (11%). Consequently, the most frequent haplotype in the population was AC (0.744), followed by GA (0.200) and AA (0.056).
