Answer

100 percent purple Explanation 1. Determine Genotypes of Parents Purebred purple is PP and purebred white is pp. 2. Perform Cross Use Punnett square to cross PP with pp. All offspring receive one allele from each parent, resulting in Pp. 3. Analyze Offspring Phenotype Pp results in purple flowers because purple (P) is dominant over white (p).

Explanation

1. Determine Genotypes of Parents<br /> Purebred purple is $PP$ and purebred white is $pp$.<br /><br />2. Perform Cross<br /> Use Punnett square to cross $PP$ with $pp$. All offspring receive one allele from each parent, resulting in $Pp$.<br /><br />3. Analyze Offspring Phenotype<br /> $Pp$ results in purple flowers because purple ($P$) is dominant over white ($p$).
