Create a Punnett Square that illustrates a cross between the following individuals:
YYSs with YySs

Fill in the following blanks to correctly represent the genotypes of the F1 generation:

YYSs :
YYss :
YySS :
YySs :

Which of the following can represent the phenotypes of the F1 generation from the cross described in the previous item? (List all that apply.)

1 yellow smooth : 1 yellow wrinkled : 1 blue smooth : 1 blue wrinkled
1 yellow smooth : 2 yellow wrinkled : 2 blue smooth : 1 blue wrinkled
12 yellow smooth : 4 yellow wrinkled
3 yellow smooth : 1 yellow wrinkled

Any help is appreciated.

What is your problem? What is so hard about to do the Punnet Square?
When you're done with that, the other will be easy ;)

Cis or trans? That's what matters.
