In a testcross involving `"F"_(1)` dihybrid flies, more parental-type offspring were produced than the recombinant-type offspring. This indicates:

Both the characters are controlled by more than one gene

The two genes are located on two different chromosomes

Chromosomes failed to separate during meiosis

The two genes are linked and present of the same chromosome.
