Answer : The genes are not linked.

Explanation : In a testcross usually one can reveal the linkage, but can't prove genes aren't linked, may be located very far apart and appear to be sorted as independent. But here, in heterozygous genes, equal number of recombinant and nonrecombinant progeny are produced reveals that the genes are not linked.
