Q

Application in genetic improvement

A
  • 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.

Q

How do we use genomics

A

-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
