When two petunia plants (night beauty) with pink flowers were crossed among themselves in the offspring

When two petunia plants (night beauty) with pink flowers were crossed among themselves in the offspring of the first generation, plants with red, pink and white flowers in a ratio of 1: 2: 1 were obtained. What kind of splitting will occur in F2 if self-pollination of F1 plants occurs? Indicate the percentage of plants with red flowers in F2. The answer is numerical, without the percent symbol, round to tenths …

The task is about incomplete dominance of genes.
With a dominant genotype, the color is red, with a recessive genotype, white, with a heterozygous genotype, pink, therefore:
P: Aa x Aa
G: (A), (a) (A), (a)
F1: AA
Aa
Aa
aa
1) With self-pollination AA
P (F1): AA x AA
G: (A) (A)
F2: AA- red 100%
2) For self-pollination Aa
P (F1) Aa x Aa
G: (A), (a) (A), (a)
F2: AA
Aa
Aa
aa
Reds – 25%
3) For self-pollination aa
P (F1): aa x aa
G: (a) (a)
F2: aa- red 0%
