Classification of genes via differentially splicing events following the gene expression patterns.

Tissues	Hybrids	Over-Dominance	High-Parent Dominance	Addictive	Low-Parent Dominance	Under-Dominance
Muscle	Mule	173	950	287	633	198
	Hinny	450	1037	311	1075	744
Brain	Mule	189	946	334	910	278
	Hinny	175	695	278	1043	333
Skin	Mule	171	828	253	578	143
	Hinny	340	866	335	1033	655

Hybrids represent mule or hinny; P, paternal lines represent male horse or male donkey; M, maternal lines represent female horse or female donkey. Additivity, mule or hinny = $\raisebox{1ex}{$1$}\!\left/ \!\raisebox{-1ex}{$2$}\right.$ (horse + donkey); non-additivity, mule or hinny > $\raisebox{1ex}{$1$}\!\left/ \!\raisebox{-1ex}{$2$}\right.$ (horse + donkey) or mule or hinny < $\raisebox{1ex}{$1$}\!\left/ \!\raisebox{-1ex}{$2$}\right.$ (horse + donkey). High-parent dominance, mule or hinny = P > M or mule or hinny = M > P; low-parent dominance, mule or hinny = P < M or mule or hinny = M < P; over-dominance, mule or hinny > P and mule or hinny > M; under-dominance, mule or hinny < P and mule or hinny < M.
