In a test cross involving F1 dihybrid flies, more parental-type offspring were produced than the recombinant type offspring. This indicates:
| 1. | chromosomes failed to separate during meiosis |
| 2. | the two genes are linked and present on the same chromosome |
| 3. | both of the characters are controlled by more than one gene |
| 4. | the two genes are located on two different chromosomes |
