Explanation:-

A question has been provided to us

We need to find the solution to the question

The correct is $1\%$. This happens due to incomplete dominance. When the red gene which is dominant is crossed with the white variety, then in the $F_1$ generation, all the flowers will be heterozygous and will have pink color. The monohybrid cross obtained does not resemble any of either of the parent, but an intermediate progeny. This happens due to incomplete dominance. Incomplete dominance is the type of gene interaction in which both alleles of a gene at a locus are partially expressed, often resulting in an intermediate or different phenotype. Incomplete dominance occurs due to non of the two alleles of a gene being completely dominant over the other. It is also known as partial dominance. Therefore, all the hybrid obtained will be of pink color.

Final Answer:-

The correct answer is $1\%$.
