Multifactorial inheritance suggests that traits such as anxiety are influenced by both genetic and environmental factors. Therefore, Janae and Sean may have inherited the genetic predisposition for anxiety, but Janae is better able to handle it due to other environmental factors, whereas Sean is not. This explains the difference in their levels of anxiety. The other choices, epilogical genetics, dominant and recessive traits, and mitochondrial inheritance, are not relevant in this scenario.
