In a cross between these two plants (mmddpp x mmddpp), all offspring in the f1 generation are wild type and heterozygous for all three traits (mmddpp). now suppose you perform a testcross on one of the f1 plants (mmddpp x mmddpp). the f2 generation can include plants with these eight possible phenotypes: solid, normal, smooth solid, normal, peach solid, dwarf, smooth solid, dwarf, peach mottled, normal, smooth mottled, normal, peach mottled, dwarf, smooth mottled, dwarf, peach assuming that the three genes undergo independent assortment, predict the phenotypic ratio of the offspring in the f2 generation. hints
