Do you know about punnet squares ?

Answer 3

In fruit flies, gray is dominant over black. If pure bred gray fruit fly crosses with a black fruit fly, what percent of the offspring will be gray? GG = homozygous gray fruit fly gg = homozygous black fruit fly

G
G
g
Gg
Gg
g
Gg
Gg

Answer 4

Genotype: Gg; Gg; Gg; GgPhenotype: Gray; Gray; Gray; Gray

Answer 5

So, what would the percentage be for Genotype and what would the percentage be for Phenotype?

Answer 6

This will be the cross of pure bred gray GG and pure bred black gg fruit flies. Since G is dominant over g can you tell me the phenotype of Gg ? @xesylady

Answer 7

@Abhisar :Jeez. thank you very much for helping me :).......The phenotype of Gg is Gray, am I right?

@thecollinjc1 Thank you very much for helping me :)......The percentage of genotype is 100% Gg while the phenotype is 100% Gray

Answer 8

yes you are correct @xesylady !
Since grey is dominant over black, Gg will give a grey phenotype.
