You examine 450 progeny from the cross in Part C and classify them according to phenotype. The results are shown in the table below.

!See Below Image!

Use these data to complete the linkage map shown below.
Drag the blue labels to the blue targets to identify the allele loci indicated by vertical dashes. Note that the apricot allele is already labeled.
Drag two of the white labels to the gray targets to identify the distances between loci. Each white label gives the distance in map units. One map unit, or one centiMorgan (cM), is equivalent to a 1% recombination frequency.

RF between AB:
39 + 42 + 5 + 4 = 90 / 450 = 20% RF

RF between AC:
17 + 19 + 39 + 42 = 26% RF

RF between BC:
17 + 19 + 5 + 4 = 45 / 450 = 10% RF

That means that the gene order is:

A----------------------B-------------C
        20 mu           10 mu

a) 20 mu
b) 10 mu
c) blunt
d) crimson
