Nwhich way does epigenetic change alter the development of a given person's phenotype?

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.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.
