Explanation:
Considering the allele for red pigment as C<em>R</em> and that for a white pigment C<em>W</em>, a pink flower will equally express both the pigments in its phenotype and will thus have a genotype of C<em>R</em> C<em>W</em>.
Crossing CR CW × CR CW you'll get,
25% C<em>R</em> C<em>R</em> - red flowers
50% C<em>R</em> C<em>W</em> - pink flowers
25% C<em>W</em> C<em>W</em> - white flowers
