Question

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

Explanation:

Step1: Analyze Punnett Square Rules

In a Punnett square, alleles from one parent go across the top and from the other parent go down the side. Each box is filled by combining the allele from the top - row and the side - column.

Step2: Check Each Box

• For box \(a\): Combining \(G\) (from top - row) and \(G\) (from side - column) gives \(GG\), which is correct.
• For box \(b\): Combining \(G\) (from top - row) and \(g\) (from side - column) should give \(Gg\), but it is filled as \(GG\), which is incorrect.
• For box \(c\): Combining \(g\) (from top - row) and \(G\) (from side - column) gives \(Gg\), which is correct.
• For box \(d\): Combining \(g\) (from top - row) and \(g\) (from side - column) gives \(gg\), which is correct.

Answer:

B.
