If the pink color of a petal is dominant over white, then when a pure pink flowered plant is crossed with a white flowered plant, all of the F1 generation plants will have pink flowers. This is because the dominant trait (pink) will mask the recessive trait (white). However, when the F1 generation plants are crossed with each other, their offspring in the F2 generation will have a 3:1 ratio of pink to white flowers. This is because each parent plant in the F1 generation carries one pink allele and one white allele, but only expresses the pink trait. When they produce gametes (reproductive cells), there is a 50% chance that the gamete will carry the pink allele and a 50% chance that it will carry the white allele. So, when the F1 plants are crossed with each other, there is a 25% chance that both parents will contribute a white allele to their offspring, resulting in a white flowered plant. The other 75% of the offspring will have at least one pink allele, resulting in pink flowers. Therefore, the color of the flower of the F2 generation would be a mixture of pink and white flowers, with a ratio of 3 pink flowers to 1 white flower. Purple and yellow are not relevant to this scenario, as the question only mentions pink and white flowers.
