http://bit.ly/PVqgcu That is the punnet square you want, just change the letters around. Genotypes are the "genes" of the offspring, while phenotypes are the "ph"ysical characteristics. Genotypes: DDCC (1/16) - Dark Curly DDCc (2/16) - Dark Curly DdCC (2/16) - Dark Curly DdCc (4/16) - Dark Curly DDcc (1/16) - Dark Smooth Ddcc (2/16) - Dark Smooth ddCC (1/16) - Light Curly ddCc (2/16) - Light Curly ddcc (1/16) - Light Smooth You can figure out the phenotypes, just add the fractions of the same physical features together.
