Solution

The correct option is B All purple
A monohybrid cross is a mating between two individuals with different alleles at one genetic locus of interest.
The cross between PP (purple flowers) and pp (white flowers) will produce pea plant having purple flowers having genotype Pp. P would be a dominant trait and p is a recessive trait, therefore plants having Pp genotype would be of purple colored.
Therefore, the correct answer is option B.
