Answer:

WwGg and wwgg

Explanation:

And even though, we can't see its color we know it has at least one allele for green (G) because of the offspring, and the other one could be green (G) or yellow (g).

The other parent was yellow so, it's both alleles only can be (ww) and (gg) all recessive.

Now we can draw a Punnet square and discover that the F1 of those parents (WwGg and wwgg) is 50% white and 50% green.
