Answer

Answer:

1:4 25

Explanation:

Step1: Define alleles

Let P be purple (dominant) and p be white (recessive). Heterozygous plants are Pp.

Step2: Set up Punnett - square

P p
P PP Pp
p Pp pp

Step3: Count genotypes

There are 1 PP, 2 Pp, and 1 pp. White - petal plants have pp genotype.

Step4: Calculate ratio

The ratio of white - petal (pp) to total offspring is 1:4.

Step5: Calculate percentage

$\frac{1}{4}\times100% = 25%$
