Genotype and Phenotype
Captions available
The idea
The genotype is an organism's genetic inheritance; the phenotype is the observable characteristics it actually develops.
In practice
Two people with the same height-related genotype reach different adult heights after different childhood nutrition.
Where people slip
Phenotype is never read off genotype alone. The environment is part of the equation, not noise around it.
