Answer:
1/4
Explanation:
Given that the F2 cross produces offspring according to the expected 9:3:3:1 ratio. 
YyRr X YyRr:
Let us break the dihybrid cross into individual monohybrid crosses. 
Yy X Yy :
     Y     y
Y  YY  Yy
y   Yy   yy
2/4 or 1/2 of the offspring are heterozygous for the trait.
Similarly, in Rr X Rr cross, 1/2 of the offspring are heterozygous for the trait.
Together, 1/2 * 1/2 = 1/4 of F2 plants are expected to be heterozygous for both traits.
