Question

using the punnett square below, which of the following is the dominant trait? 10 pollen b b b bb bb pistil ♀ b bb bb a pollen b pistil c purple d white

Explanation:

In genetics, a dominant trait is one that is expressed in the phenotype when at least one dominant allele is present. In the Punnett - square, the genotypes BB and Bb result in purple flowers, while the genotype bb results in white flowers. Since the presence of the B allele (either in homozygous BB or heterozygous Bb form) leads to the purple - flower phenotype, purple is the dominant trait.

Answer:

C. purple
