Multiple Choice

Please use the following information to answer the question(s) below.
A plantlike organism on the planet Pandora can have three recessive genetic traits: bluish leaves, due to an allele (a) of gene A; a feathered stem, due to an allele (b) of gene B; and hollow roots due to an allele (c) of gene C. The three genes are linked and recombine.
A geneticist did a testcross with an organism that had been found to be heterozygous for the three recessive traits and was able to identify progeny of the phenotypic distribution (+ = wild type) shown in Figure 12.3.

Figure 12.3 -The greatest distance among the three genes is between a and c. What does this mean? A)  Gene c is between a and b. B)  Genes are in the order: a-b-c. C)  Gene a is not recombining with c. D)  Gene a is between b and c. E)  Distance a-b is equal to distance a-c. Figure 12.3
