In the mathematical field of differential geometry, the Gauss–Bonnet theorem (or Gauss–Bonnet formula) is a fundamental formula which links the curvature of a surface to its underlying topology. In the simplest application, the case of a triangle on a plane , the sum of its angles is 180 degrees. [ 1 ]
One version produces yellow dogs, and a mutation produces black. All dog coat colors are modifications of black or yellow. [2] For example, the white in white miniature schnauzers is a cream color, not albinism (a genotype of e/e at MC1R.)
