Body Color: Red (R) and Gold (AU)
The hypothesis is that the dihybrid cross of an Acid (AC) and Gold (AU) purebred parent with a Lightning (LT) and Red (R) purebred parent will result in an F1 generation that expresses only the dominant trait (1:0 ratio of dominant-dominant). The dominant traits are Acid and Gold, and the hidden, recessive traits are Lightning and Red. In the F-2 generation, there will be a 9:3:3:1 ratio of dominant-dominant, dominant-recessive, recessive-dominant, and recessive-recessive. The cross is a simple Dominant/Recessive inheritance.
