Garden asparagus, Asparagus officinalis, produces either
staminate (male) or pistillate (female) plants in about equal
numbers. Occasionally, stamens develop in pistillate flowers and
pistils in staminate flowers. Although these latter pistels on the
male plant are usually non-functional, they sometimes produce
viable seed by self-fertilization. From self-fertilization, 198
such seed were obtained. Of these, 155 were male and 43 female.

gave male progeny only and 17 gave progeny in a 1 male to 1 female
ratio
3) Wht further information does this give you?
