A test cross of a female mouse that was heterozygous at the three loci A B C to a male that was homozygous recessive at all three loci resulted in the offspring listed below. + + + 105 + +c 6 +b+ 319 +bc 71 a ++ 74 a +c 321 ab+ 4 abc_100 1000 From the data presented above calculate the genetic map distance between a and c. Select one: O A. a and c are unlinked and map units cannot be calculated O B. between 17.1 and 28.6 map units C. between 0 and 17 map units O D. between 28.7 and 35 map units O E. between 35.1 and 49.9 map units
