Question

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

Explanation:

In a Punnett square, we combine the alleles from each parent. One parent has alleles \(D\) and \(d\), and the other also has \(D\) and \(d\). When we fill the Punnett square:

• For the top - left box: \(D\times D = DD\)
• For the top - right box: \(D\times d=Dd\)
• For the bottom - left box: \(d\times D = Dd\)
• For the bottom - right box: \(d\times d=dd\)

Looking at the given Punnett square, box \(a\) should be \(Dd\) (since it is the combination of \(D\) from one parent and \(d\) from the other), but it is filled as \(DD\).

Answer:

a.
