Abstract excerpt
A FecX-mutated allele called FecXR in the BMP15 gene has been described in Rasa aragonesa sheep. FecXR causes increased prolificacy when heterozygous and sterility when homozygous in ewes. However, highly prolific ewes without the FecXR allele have been found in this breed. Therefore, a genome-wide association study (GWAS) was performed in 158 ewes (tail H: N = 73, mean prolificacy ± standard...
