Does GgAa x GgAa make a 9:3:3:1 cross?

and what does Ggaa x GgAa make?

Lets assume for both of these questions that
G=dominant
g=recessive

A=dominant
a=recessive

THANX, DAT tomorrow and i and forgetting the most obvious details of genetics.

Any dihybrid cross between two heterozygous traits will yield a 9:3:3:1 phenotype offspring.

GgaaxGgAa gives you

2 GGAa
2 GGaa
4 GgAa
4 Ggaa
2 ggAa
2 ggaa

what does Ggaa x GgAa make?
1/8 GGaA, 1/4 GgaA, 1/8 ggaA, 1/8 GGaa, 1/4 Ggaa, 1/8ggaa.

good luck tomorrow Rozhon
