Fisher's so-called fundamental theorem of natural selection:atural "The rate of incr"The rate of increase in fitness of any organism at any time is equal to its genetic variance in fitness at that time."

Epigenetics From Wikipedia: “Epigenetics is the study of heritable changes in gene expression or cellular phenotype caused by mechanisms other than changes in the underlying DNA sequence.” Is epigenetics why cloned animals don’t fare well?
