Which of the following terms refers to how genetic traits are expressed?

A. Display

B. Genotype

C. Phenotype

D. Dominance

The correct answer is Phenotype - C.

A phenotype is the expression of our genes that is also shaped by our environment.

While we surely are predisposed to certain states due to our genetics, we are at the same time co-determined by our environment and their interaction. It is very hard to take these two factors apart. However, the correct answer indeed is C in this case.
