Short summary
Sequencing of the GDF9 gene in 16 twin-birth, 4 triplet-birth, and 2 infertile ewes from Iranian sheep with verified segregation of G2–6 mutations, as well as a new G0 mutation, C25T, which causes L9F substitution in the signal peptide region. None of the triplet-birth or infertile ewes carried the G1, G4, G7, FecGE, G8, or FecGT mutations. In addition, using a large dataset comprised of 605 individuals showed a significant difference in the abundance of G1 and G4 mutations between breeds.
