What is the most probable inheritance pattern of a trait with gaussian proportional distribution of phenotypical forms?

If a trait statistically has a normal (bell-shaped curve, gaussian) distribution of its phenotypical forms it is likely that it is conditioned by the polygenic inheritance (quantitative inheritance).

In the quantitative inheritance the effects of several genes add to others making it possible to represent the trait variation of a given population in a Gaussian curve with the heterozygous genotypes in the center that is the appearing in larger number, and the homozygous in the extremities.
