Researchers have suggested that certain genetic variations make adolescents more or less susceptible to environmental influences. this is known as:

The genetic variations that make adolescents more or less susceptible to environmental influences may in certain circumstances be considered immune transference. The parents can transfer antibodies and certain gene traits that provide their offspring with immunity to certain diseases. In this case, the adolescent may be protected from diseases such as certain cancers, communicable diseases like MMR, and not affected by chemicals that the parents developed a resistance to by environmental exposure. In the opposite case, adolescent children may be more susceptible to specific cancers, heart disease, obesity, and substance abuse due to the gene variations passed from parent to child. The child may react to chemicals that have caused reactions in their parents.
