Not enough info has been provided here. You would have to indicate what R and G represent, and what the various phenotypic outcomes could be, in order to determine the percentages.
3:1
All you need to do is use a Punnet Square for this. You will get the following genotypical and phenotyical ratio from this cross: RrBb x RRbb = RRBb RrBb RRbb Rrbb In terms of phenotypical ratios, 50% of the offspring have a chance of showing R and B, and the other half have the chance of showing R and b.

The Standard State of an element is defined as pure, at 1 atmosphere pressure, and in the phase it would normally occur at 298K. Thus, the standard state of Argon is Ar(gas), Oxygen is O2 (gas), Carbon is C(solid, graphite), and Bromine is Br2 (liquid). :)(: rrgg the derpasorous rex iz gonna eat u... say this is usefull :)))
