Solution-Humans and the genes occur on different chromosomes

Freckles (F) and six fingers (S) are dominant alleles in humans and the genes occur on different chromosomes. If an FfSs male and an FfSs female have a WHOLE BUNCH of kids, Here are the expected ratios below.

9: freckles/ 6 fingers

3: freckles/ no 6 fingers

3:no freckles/ 6 fingers

1: no freckles/ no 6 fingers

Question: If the P generation of this cross were FFSS and ffss, AND the gene for freckles and finger # were on the SAME chromosome, which of the phenotypes above should not show up in the F2 (assume no crossing over)?
