🧵 Why do heritable traits fit a normal distribution?

I don't see how this makes sense using Mendelian inheritance. Is it because of the heterogeneity in a population and random gene inheritance from two parents to their offspring, or random mutations that aren't deleterious?

Polygenic traits --> many factors ---> central limit theorem

Unless there is a mechanistic factor that prevents the distribution from being normal.
