DNA testing in sheep can be used to verify parentage, help screen for undesirable mutations and assist in making the right breeding decisions for the herd. Genomic testing using chip-based technologies can also be used to develop genomic predictions and genomically enhanced breeding values.
Neogen®'s genomic testing solutions for sheep include:
- Genetic recessives and causative mutations
- Genome-wide selection
- Determination of genetic merit
- Identification of quantitative trait loci (QTL)
- Comparative genetic studies
The GoatSNP50 chip utilizes more than 50,000 SNP variants to provide uniform genomic coverage. The array was developed by the International Goat Genome Consortium who screened whole genome sequencing data in the following goat breeds: Alpine, Boer, Creole, Katjang, Saanen and Savanna. A total of 10 breeds were used to validate the 52k SNP content.
The OvineHD array includes more than 600,000 genomic variants designed by the International Sheep Genomics Consortium (ISGC). The array includes nearly all the content from the original OvineSNP50 array. This higher density array will dramatically increase the power to identify key genes responsible for the desired measured traits.
The OvineLD chip includes approximately 15,000 SNPs and is used to accurately impute up to the higher density Ovine arrays. In addition, the chip also contains many additional genetic recessive and causative SNP content.
OvineSNP50 Genotyping BeadChip
The OvineSNP50 BeadChip array features over 54,241 evenly spaced probes that target SNPs, offering more than sufficient SNP density for genome-wide association studies and other applications such as genome-wide selection, determination of genetic merit, identification of quantitative trait loci, and comparative genetic studies. The OvineSNP50 BeadChip provides uniform genome-wide coverage with a mean gap of 46kb.
Other genetic tests available:
- Ovine progressive pneumonia virus (OPPV) susceptibility
- Scrapie susceptibility
- Spider lamb
- SNP parentage
Create assays tailored directly to your specific needs for targeted region genotyping, validation studies, association studies, or marker-assisted breeding programs. Neogen offers custom Illumina Infinium BeadChips and Affymetrix Axiom Arrays as well as less dense marker-assisted selection panels.
