An organism has characteristics that display incomplete dominance. If Parent A is \( ww \) for white petals and Parent B is \( WW \) for red petals, which of the following predicts the offspring?

A. Half of the offspring would have white petals and half would have red petals.
B. The offspring would have \( WW \) alleles, and all would have red flower petals.
C. The offspring would have \( ww \) alleles, and all would have white flower petals.
D. The offspring would have \( Ww \) alleles, and all would have pink flower petals.

In incomplete dominance, offspring of parents with genotypes ww (white petals) and WW (red petals) would all have the genotype Ww and display pink flower petals, expressing a phenotype that is a blend of both parents.

Explanation:

Incomplete dominance in genetics is a situation where the phenotype of the offspring is a blend of the phenotypes of the parents. To answer the question: If parent A has genotype ww for white petals and Parent B has genotype WW for red petals, the offspring resulting from their cross would all have the genotype Ww.

This is because they inherit one allele from each parent. According to the principles of incomplete dominance, neither allele is completely dominant over the other.

Consequently, these offspring will not have red or white petals, but rather, a blend of both, which results in pink flower petals. Therefore, the correct prediction for the offspring would be: d. The offspring would have Ww alleles, and all would have pink flower petals.
