The primary reason why the symptoms will not be the same is because the environment of the twins’ bodies can be very different.

Research from the National Institutes of Health (NIH) indicates that “genetic predisposition to infectious diseases may be modified by environmental and lifestyle factors” (Ren, et al., 2021). Even though twins have the same genetic code and environment, they can experience different viral experiences. Research from University of Michigan 2020 found that identical twins may experience COVID-19 at different severity levels. The reason is that even though they share the same genetic code the virus can cause different reactions in each individual depending on how their immune systems react to it. Cont….
