Genomics Flashcards
Genomic Definition
Study of how DNA of any species is organized and expressed as traits
Application in genetic improvement
- Find easily detected genetic differences among animals
*Develop SNP (single nucleotide polymorphism) panels to detect those differences - Relate SNP differences to productivity differences
*Use best animals as parents of the next gen.
Federal Support of genomics
Cattle
Sheep
Swine
Poultry
Horses
Aquaculture
How do we use genomics
-Identify DNA sequences associated with disease resistance and production traits
-Animals can be evaluated as soon as DNA can be obtained
-Best animals to be parents can be determined earlier and more accurately
Genetic Markers Definition
Segment of DNA at a unique physical location in the genome that varies sufficiently between individuals that its inheritance can be tracked through families
Genetic markers’ jobs
- Allow inheritance to be followed in a region across generations
[SNPs are markers of choice]
Revolutionizing animal breeding
genomics
Used extensively in dairy cattle breeding
Genomic selection
Support detection of parentage and other errors
High quality genotypes
Important for Success
International collaboration
