In cucumbers, heart-shaped leaves (hl) are recessive to normal leaves (hl) and having numerous fruit spines (ns) is recessive to having few fruit spines (ns). the genes for leaf shape and for number of spines are located on the same chromosome; findings from mapping experiments indicate that they are 32.6 m. u. apart. a cucumber plant having heartshaped leaves and numerous spines is crossed with a plant that is homozygous for normal leaves and few spines. the f1 are crossed with plants that have heart-shaped leaves and numerous spines. what phenotypes and phenotypic proportions are expected in the progeny of this cross?
