25%

Explanation:

1/4 and 25% is the answer

If both parents are heterozygous for the same trait, it means that both parents have both of the alleles, one for purple petals and one for white petals, so the crossing will lead to an offspring that will present the following genotype proportions:

Purple-colored petals (dominant characteristic, both alleles dominant) - 1/4

Purple-colored petals (dominant characteristic, one allele dominant, one allele recessive) - 2/4

White-colored petals (dominant characteristic, both alleles recessive) - 1/4

Mendel crossed the dominant purple colour flowered plant with the recessive white colour flowered plant. The F 1 generation produced the heterozygous purple colour flowered (Pp) plants. When two heterozygous pea plants (Pp) are crossed in the F2 generation represented by Pp x Pp, the gametes formed are P and p. Out of the offspring produced, 3 are purple colour flowered plants and 1 is white colour flowered plant. Thus the phenotypic ratio is 3: 1 with one out of four plants being white colour flowered pea plant. When expressed in percentage it is 25%.

White-colored petals (dominant characteristic, both alleles recessive) - 1/4

The ratio of offspring to have white petals will be 1/4 - 25%.

P= purple petal color (dominant)
p=white (recessive)

Pp(heterozygous)

50%

Ratio: 50:50
