Megan's mother suffered from the flu during her pregnancy with megan. statistically, this increases megan's risk of developing schizophrenia later. this is an example of a(n) factor, meaning a heritable change that is not due to dna.

Epigenetic

Explanation:

Epigenetic factors are factors that cause heritable changes in the expression of genes and not as a result of the DNA sequence of an individual. Factors such as lifestyle, age, complications during pregnancy etc, can have influence on the expression of genes as there is a change in a phenotype rather than the genotype being influenced.

Statistically, several studies have shown that complications during pregnancy increases the chance of a baby developing schizophrenia later on in life. Megan’s mother having suffered from flu during her pregnancy with Megan is an epigenetic factor that increases Megan’s chances of suffering from schizophrenia later.
