Explanation:

Step1: Analyze Punnett square rules

In a Punnett square, alleles from one parent go along the top and from the other parent go along the side. When filling the boxes, we combine the alleles from the top and the side.

Step2: Check each box

• For box a: Parent 1 (G) and Parent 2 (G) → \(GG\) (correct).
• For box b: Parent 1 (G) and Parent 2 (g) → \(Gg\) (incorrect as it's filled with \(GG\)).
• For box c: Parent 1 (g) and Parent 2 (G) → \(Gg\) (correct).
• For box d: Parent 1 (g) and Parent 2 (g) → \(gg\) (correct).

Answer:

B.
