In Cacti one gene determines whether the cactus will have spines (S dominant) or no spines (s recessive). A second gene determines whether the spines are pointed (P dominant) or dull (p recessive). The genetic cross SSpp x ssPP creates F1 offspring with genotype SsPp. Two dihybrid F1 offspring are crossed. Write the expected genotypes (include what percentage of each) and the expected phenotypic ratio in the F2 generation assuming the genes are linked on the same chromosome and there is no crossing over.
