Yes, there will still be a chance for the F2 generation to have a ratio 9:3:3:1

Explanation:

According to Mendel's law of segregation, alleles of a gene pair separate at the time of game formation.

According to the Law of independence, the alleles sort independently into the gametes.

Even if the two traits under study are located on the same chromosome, they will segregate and assort independently at the time of gamete formation.

Also, at the time of meiosis, one of the alleles will arise from each parent hence there will still be a chance for the F2 generation to have a 9:3:3:1 ratio.
