The idea
Growth and development is the property by which genetic instructions direct an organism from its start toward the form typical of its species.
In practice
A kitten's genes direct it toward the same general shape and behavior as its parents, though no two kittens turn out identical.
Where people slip
Genetic instructions set the pattern; they do not remove all variation between individuals of the same species.
