Answer:
Gene-environment interactions.
Explanation:
In gene-environment interactions, the field of epigenetics looks beyond the genotype itself and studies how the same genotype can be expressed in different ways. Scientists studied how the same genotype can turn out to be very different phenotypes. Gene expression is most of the time influenced by the environment in ways that are not always obvious. As we see in this case, identical twins share the same genetic information, their genetic material is exactly the same, but even with identical genes, there can be an incredible amount of difference in how gene expression can turn out throughout each twin’s life, one with schizophrenia and one completely healthy mentally.
