Roses are Red

In the species of violet Viola granulanica, the allele Y is responsible for pigmentation of the petals and the allele X is responsible for petal shape. The dominant allele Y creates a red pigmentation in the petals, and a homozygous recessive pair of this allele will result in blue petals. The dominant allele X creates pointed petals, and a homozygous recessive pair of this allele will result in rounded petals.

If a flower with the alleles YyXX and a flower with the alleles YyXx breed, what percent of the offspring will have blue-pointed petals?
