Gene S controls the sharpness of spines in a type of cactus. Cactuses with the dominant allele,
S, have sharp spines, whereas homozygous recessive ss cactuses have dull spines. At the
same time, a second gene, N, determines whether cactuses have spines. Homozygous
recessive nn cactuses have no spines at all

a.
incomplete
dominance. d.
pleiotropy.
