Multifactorial inheritance suggests that traits such as anxiety are influenced by both genetic and environmental factors. This concept accounts for the variation in anxiety levels between Janae and Sean, as they may have inherited different combinations of genes that predispose them to anxiety, and may have been exposed to different environmental stressors throughout their lives. Epigenetic genetics, dominant and recessive traits, and mitochondrial inheritance do not specifically address the role of genetic and environmental factors in complex traits like anxiety.
