Gene Interactions
When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.
Gene Expression
Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
An elementary school student comes down with a stomach virus the day after she swims at the local pool. Her father warns other parents at the school that the pool is unsanitary and causes virus to spread. What should the parents conclude? Choose the best answer.

There is an association between people visiting the pool and increased reports of viruses. There is no association between people visiting the pool and increased reports of viruses. Nothing can be concluded because this is an anecdote.
