In this example, we are looking at making our heterozygous for the Candy gene. This example, we are breeding a visual Candy animal to Normal animal. In this version of the Punnett Square, the visual Candy is represented by CC and the Normal is represented by nn.
The resulting off spring will be 4 normal animals that are heterozygous for the candy gene. Other wise known as het candy, this is represented by nC.
