Reproduction of Awassi and Hamdani Sheep Is Associated With a Novel Missense SNP (p.24Ile>Thr) of the Gene.

Objectives: Litter size is a crucial economic factor in the sheep industry. Several factors and genes influence litter size, making the identification of genes or loci involved a genetic challenge. Gonadotropin-inhibitory hormone () is one of several genes that influence sheep's reproductive traits.

Variation in the gene G203A is associated with Awassi and Hamdani sheep fertility.

Arylalkylamine-N-acetyl-transferase () is one of several genes that influence sheep reproduction. Thus, the objective of this study was to investigate whether genetic variability within the gene influenced the reproductive performance of Awassi and Hamdani ewes. A total of 99 twin and 101 single-progeny ewes were analyzed for genomic DNA.
