Question

the punnett square illustrates a cross for color of the flower. based on the phenotypes and genotypes of these offspring, it is clear that purple flower color allele is and the parents are select the correct answer from each drop - down menu. heterozygous homozygous dominant homozygous recessive reset next

Explanation:

Step1: Analyze Punnett - square genotypes

In the Punnett - square, we have genotypes Bb (purple) and bb (white). The presence of the B allele in Bb results in the purple phenotype, while the double - recessive bb results in the white phenotype.

Step2: Determine allele dominance

Since the Bb genotype shows the purple color, the purple flower color allele (B) is dominant. The parents' genotypes must be such that they can produce both Bb and bb offspring. The only way is if the parents are heterozygous (Bb).

Answer:

The purple flower color allele is dominant and the parents are heterozygous.
