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.

Explanation:
The term gut microbiota refers to microorganisms such as, for example, bacteria, fungi, etc., that live in the gastrointestinal (GI) tract of humans.

Moreover, there are GI bacteria that play roles in the metabolism of bile acids and sterols. Finally, intestinal bacteria from a group named Proteobacteria produce gas, this group is especially in the guts of colicky babies, where cause pain and lead to crying.
