I noticed that taller parents have taller kids, which is similar. I wonder if there's some kind of mechanism underneath both correlations.
Probably because of genes and access to nutritious food.
You can already see this in a lot of kids and recognize their parents through it.
There are probably plenty of examples of kids in foster care who do not share those behavior patterns
