It’s a different formula for females.
So far genetic research is showing that height is 80% genetics. They’ve also found many genetic mutations that can cause extreme height or extreme lack of height. It’s not as simple as mother’s height or father’s height. Not with thousands of genes involved in height.
Imagine in the future they manipulate every fetus’s genes to make all males the same height and all females the same height. Creepy thought.
