Answer
50%. Without knowing about the physical linkage of the genes, you would think that the genes are unlinked since the results would be the same for genes on different chromosomes.
Work Step by Step
The percent recombinants will match the map distance: 1 cm = 1% recombination. Review earlier material on Mendelian genetics to see that 50% of the time new combinations would occur with genes on separate chromosomes.
