Hi Tomaz,
is a simulation study what you are looking for? A paper like this maybe:
http://www.sciencedirect.com/science/article/pii/S0040580903000078 not sure
it can help you, but they explored a bit the effect of sample size and
number of alleles on likelihood-based inferences for inbreeding coefficient
(in the middle of a lot of mathematics :/)
ciao
Valeria
