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 as follows:

A geneticist did a testcross with an organism that had been found to be heterozygous for the three recessive traits and she was able to identify progeny of the following phenotypic distribution (+ = wild type):
Phenotypes   Leaves   Stems   Roots   Number
1   a   +   +    14
2   a   +   c    0
3   a   b   +    32
4   a   b   c    440
5   +   b   +    0
6   +   b   c    16
7   +   +   c    28
8   +   +   +    470
         Total   1,000

57) Which of the following are the phenotypes of the parents in this cross?
A) 2 and 5
B) 1 and 6
C) 4 and 8
D) 3 and 7
E) 1 and 2
