Human Growth and Development / Unit 1 HGD 0012 short lesson, about 20 seconds
Heritability Estimates
Captions available
The idea
A heritability estimate is the extent to which genetic differences explain differences in a trait across a group of people.
In practice
Differences in a trait across many people, split into genetic and environmental shares.
Where people slip
It says nothing about one person. A heritability estimate never tells you how much of your own trait comes from your genes.
