Question

If the first-generation offspring are crossed to each other, what will the punnet square of this cross look like?

Answer 1

dihybrid or monohybrid?

Answer 2

1/4 will express the recessive trait and 3/4 will express the dominant trait.
That means given two filial 1 generations for one trait such as eyes (Gg, Gg), the resulting punnet square will be GG, Gg, Gg, and gg.

Answer 3

That's for a monohybrid cross.

Answer 4

It depends what cross produced "the first generation offspring."

Answer 5

Yes, you should also specify what the cross looks like. I'm basing my reply off of what's generally taught in my biology class as a basic example.

Answer 6

Your question is not complete. I need info on parents' genotype
