7.5.2 Test (CST): Computer Scored Unit Test A plant can have either broad leaves (8) or narrow leaves (b). A plant with

genotype Bb is crossed with a plant with genotype Bb. Which Punnett square

correctly represents this cross?

            B                  b

B          BB               Bb

b          BB               bb

Explanation:

From the given information;

A plant can have either broad leaves with  allele  B

Or

Narrow leaves with allele b

NOW;

A plant with  genotype Bb is crossed with a plant with genotype Bb.

Which Punnett square  correctly represents this cross?

Let's first understand that when this question was posted , there was no diagram attached to it showing the options of different Punnett square from which we can pick the right answer BUT,  we will answer the question by showing  a schematic view of how the Punnett Square looks like, then students can choose the right option themselves.

Let's recall

A plant with  genotype Bb is crossed with a plant with genotype Bb.

The Punnett square for this cross is as follows:

            B                  b

B          BB               Bb

b          BB               bb
