Answer:
Aa and Aa (can be any other letter, but both need to be heterozygous)
Explanation:
1 out of 4 offspring from the cross are white, so to verify that the genotypes of the parents are correct we can do 1÷4×49 (number of plants) and that equals 12.25, which is close enough to 11. So the genotypes of the parents are Aa and Aa.
