“Epigenetics” as introduced by ConradWaddington in 1946, is defined as a set of interactions between genes and the surrounding environment, which determines the phenotype or physical traits in an organism, (Murrell et al., 2005;Waddington, 1942). Initial research focused on genomic regions such as heterochromatin and euchromatin based on dense and relatively loose DNA packing, since these were known to contain inactive and active genes respectively, (Yasuhara et al., 2005). Subsequently, key roles of DNA methylation, Histone Modifications and other assistive proteins such as Methyl Binding Proteins (MBP) during gene expression and suppression were identified, (Baylin & Ohm, 2006; Jenuwein & Allis, 2001). An emergent and persistent view that.
