question 43

Multiple Choice

B and c 0.19%
What is the correct conclusion from this data?

• A)Genes b and c are farthest apart.
• B)Gene order is c, b, a.
• C)Cotransformation of b and c is so frequent, they must be one gene.
• D)Gene a is closer to b than to c.
• E)Genes a and c are farthest apart.
