This is how you do it: Parent genotypes could be Aa x Aa (or whatever letter you'd like to use)
Phenotypic ratio 1 homozygous dominant(red flower) : 2 heterozygous(red flower) : 1 homozygous recessive(white flower)
Genotypic ratio for a heterozygous cross will always be a 1:2:1 ratio
The answer should be 1:2:1
