If the distance between vestigial and curly is 13 cM And the

If the distance between vestigial and curly is 13 cM. And the distance between bubblegum and vistigial is 7 cM. Which of the following maps is correct? Map #1 Map #2 You need more information to determine which map is correct

Solution

Answer is C,

We need more information to predict the map, becuase the chromosome map distance between bubble gum and vestigal is 7cM and vestigal and curly is 13cM, so between the vestigal and curly is bubble gum ie..map1, but it cannot determine as map1 because the specific points on the map needed to predict, 13-7=6cM, between vestigal and bubble gum, bubble gum and curly is 7cM respecitvely.
