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.

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

and what does Ggaa x GgAa make?

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

YES

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 👍

damn tinman beat me to it. 🙂 btw your dog looks cool with that party hat
I have the same ratios. you just need to convert them to whole numbers

yup thats wat i get..!!!

ditto

 

[dontbam]

what? dont u only get "1" for the recessive ggaa according to 9:3:3:1?

9: G-A-
3: ggA-
3: G-aa
1: ggaa

edit: okay oops, i failed to see tinman wrote GgaaxGgAa,

pardon me!
