In a flowering plant, blue flower (B) trait is dominant to white flower (b) trait. A true-breeding blue flower plant (BB) is crossed with another true-breeding white flower plant (bb). What percentage of offspring are expected to have blue flowers? Choose 1 Choose 1 (Choice A) A 000 percent (Choice B) B 505050 percent (Choice C) C 757575 percent (Choice D) D 100100100 percent

The correct answer is:

100100100 percent (D)

Explanation:

To begin, let us express the alleles for each trait:

Blue flower (B) (dominant)

White flower (b) (recessive)

Parents:

1. True breeding blue flower (BB)

2. True breeding white flower (bb)

Now let us do the crossing:

                  b              b

B                 Bb           Bb

B                 Bb           Bb

From the cross, it is seen that out of 4 offspring, the genotypes were 'Bb' while are flowers that are phenotypically blue in color. Hence, all the offspring have blue flowers.

decomposers, parasites, predators, and bacteria
