distribution for ratios?

we are trying to run a meta-analysis on factors affecting heritability in 
MCMCglmm.

I'm surprised no-one has suggested a bivariate analysis of V_g and 
V_e (gamma, or even gaussian).

"... the so-called co-efficient of heritability, which I regard as one of 
those unfortunate short-cuts, which have often emerged in biometry for 
lack of a more thorough analysis of the data."
