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 cross between a true-breeding sharp-spined cactus and a spineless cactus (ssnn) would produce what types of offspring?
