Question

sarah is practicing punnett squares. based on this sample, which box did she not fill out correctly?
options:
d.
b.
a.
c.

Explanation:

Step1: Analyze Punnett Square Rules

In a Punnett square, the gametes from one parent are placed on the top and from the other on the side. Each box is filled by combining the corresponding gametes.

Step2: Check Each Box

• For box \(a\): Combining \(G\) (from top) and \(G\) (from side) gives \(GG\), which is correct.
• For box \(b\): Combining \(G\) (from top) and \(g\) (from side) gives \(Gg\), not \(GG\). So this box is incorrect.
• For box \(c\): Combining \(g\) (from top) and \(G\) (from side) gives \(Gg\), which is correct.
• For box \(d\): Combining \(g\) (from top) and \(g\) (from side) gives \(gg\), which is correct.

Answer:

b.
