Understanding Non-Mendelian Inheritance Patterns

A researcher is studying a newly discovered gene associated with a hereditary condition affecting the susceptibility to certain diseases. This gene exhibits a pattern of inheritance that is not strictly Mendelian. After analyzing a family pedigree, the researcher notes that the trait appears in every generation, with both males and females equally affected. Further analysis reveals that the gene can be silenced by environmental factors, suggesting the role of epigenetics in disease presentation. Based on this information, which of the following statements is the most likely description of the inheritance pattern of this gene?
