One Problem with the Genotype-As-A-Blueprint Analogy Is That

One problem with the genotype-as-a-blueprint analogy is that:

A) environmental factors influence the actual phenotype displayed.
B) even though genes directly control physical development and behavior, the final result is never predictable.
C) the genotype does not direct and control any aspect of development as it unfolds over the lifespan.
D) environmental factors have little or no influence on the phenotype displayed.
