During a 30 year period, the yearly frequency of drought is 10%, which is experienced in three separate years.

Explanation:
Codominance is where both traits show, and in this case, with the red and blue, they show. Incomplete dominance is characterized by blending; in that case, the fish would have to be purple because red and blue make purple. It's not multiple alleles because there isn't anything to suggest that there are more than 2 alleles for the color gene.
Drugs and other chemicals are examples of how environmental factors affect gene expression. These drugs can either 'activate' or 'inhibit' the expression of genes that you have. For example, taking drugs while being pregnant affects the genetic makeup of the baby inside you.
