Transgressive phenotypes observed in hybrids are a result of non‐additive genetic interactions that lead a phenotype in the progeny that is more extreme than either parent; the molecular basis of this phenomenon is unclear. New evidence implicates small RNAs and epigenetics in this deviation from Mendelian inheritance patterns.
