The first scientific discovery is the epigenetic variation where it describes the deviation in the chemical tags that attach to DNA which affect how genes are read. Theses tags are called epigenetic markings that act as switches that control how genes can be read. Another essential discovery on human variation is the genetic variability, which measures the tendency of individual genotypes in a population to become different from one another. In addition, the variability of a trait is how much that characteristic tends to vary in response to environmental and hereditary influences.

The initial exposure of the body to an infectious agent e.g. through a vaccine, triggers an immune response most of which rapidly diminishes after the vaccination. However some cells of the immune system called lymphocytes remain with a memory of that pathogen.As a result, if the same pathogen infects a vaccinated person, the memory cells remember and recognize it and rapidly spring into action triggering a much more rapid response specific to that pathogen than the initial exposure, effectively dealing and neutralizing the pathogen.
Sickle cell sickness might've been identified with her passing since her body and cells weren't getting enough oxygen. Indications more often than not don't happen until after the age of 4 months. All individuals with sickle cell iron deficiency have excruciating scenes called emergencies. These can last from hours to days,
