Question

What is the most likely inheritance pattern of a trait with Gaussian proportional distribution of phenotypic forms?

Answer 1

If a trait statistically has a normal (Gaussian, bell curve) distribution of its phenotypical forms, it's far in all likelihood that it's miles conditioned by means of polygenic inheritance (quantitative inheritance).

In quantitative inheritance, the results of several genes are delivered to others, making it viable to symbolize the trait version of a given population in a Gaussian curve with the heterozygous genotypes in the middle, this is, those who appear in large number, and the homozygous ones at the ends.
