A testcross was done to check for genetic linkage between the genes for these traits, with the following results for the offspring:


410 flies with long wings and a black body

105 flies with long wings and a grey body

390 flies with vestigial wings and a grey body

95 flies with vestigial wings and a black body


Which of the following best represents the map distance between the genes for these two traits?
