Reason scientist can say traits are a result
of both genes and environment
Scientist have studied identical twins to
determine the affects of environment and
genes
Identical twins have the same DNA
If DNA was the only factor that
determined who we are, then identical
twins would be identical in every way.
Environmental factors like diet, exercise,
time spent outdoors, and schooling also
affect who an individual becomes.
