Question

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

Explanation:

Step1: Analyze Punnett Square Rules

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

Step2: Check Each Box

• For box \(a\): If one parent has \(D\) (from the top - row) and the other has \(d\) (from the side - column), the combination is \(Dd\), which is correct.
• For box \(b\): If one parent has \(D\) (from the top - row) and the other has \(d\) (from the side - column), the combination is \(Dd\), which is correct.
• For box \(c\): If one parent has \(d\) (from the top - row) and the other has \(d\) (from the side - column), the combination should be \(dd\), but it is filled as \(Dd\), which is incorrect.
• For box \(d\): If one parent has \(d\) (from the top - row) and the other has \(d\) (from the side - column), the combination is \(dd\), which is correct.

Answer:

C.
