Question

The Punnett square predicts the ratio of genotypes in the offspring based on the genotypes of the parents. Which Punnett square represents a cross between a mom who is heterozygous for dimples and a dad who is homozygous for no dimples?

A Punnett square is shown. The columns are labeled Upper D and Upper D. The rows are labeled d and d. Clockwise from upper left the boxes contain: Upper D d, Upper D d, Upper D d, Upper D d.

Answer 1

Hey there!

Here is your answer:

Since there are not options im going to go with what i know:

(Alleles)

heterozygous: A,a

homozygous: a,a

Therefore the Punnett square should look like this:

A, a

a IA,a I a,a

a IA, a I a, a

Therefore the answer is 50% A,a , and 50% a, a!

If you need anymore help feel free to ask me!

Hope this helps!
