This study aimed to examine the polymorphism of the BMP15 (FecX $^{G} $ and FecX $^{I}
$) and GDF9 (G1 and G4) genes and the association between genotypes and litter size in …

The main purpose of this study was to assess the presence of the previously reported single
nucleotide polymorphisms (SNPs) in the sheep growth differentiation factor 9 (GDF9) and …

The incidence of mutation in three loci of GDF9, BMP15 and BMP15-1B and their effects on
litter sizes was evaluated in Baluchi sheep. Wild-type alleles were detected for BMP15 and …

Litter size is an economically important trait in sheep breeding. The objectives of this study
were as follows:(1) to ascertain if any of the 19 known variants in the BMPRIB, BMP1 5, and …

This study was carried out to determine the presence of polymorphisms in genes affecting
litter size. The SNPs in bone morphogenetic protein receptor type 1B (BMPR1B), bone …

The objective of this study was to investigate association between GDF9 and BMP15 gene
polymorphism and litter size in fat-tailed sheep, a total of 97 mature ewes from four breeds …

Kazakh meat–wool sheep are of great interest because of the intrabreed multifetal type's
high productivity of 140%–160%. Genes encoding growth differentiation factor-9 (GDF9) and …
