Epigenetics are variations in gene expression that does not contain
changes to the principal DNA sequence. Therefore, it is a alteration in
phenotype without a modification in genotype. With this, all traits
are considered epigenetic, the production of genetic and non-genetic effects,
begins with methylation at conception, which will then continue throughout the
life.
Genotype - the total genetic constituent of an individual
phenotype - the expressed shown characteristics is called phenotype

All DNA of creatures is made from the same materials, and is largely the same. (Humans are less than 5% different than primates genetically)
