SUPPORTED
the evidence backs this
confidence 93/100
Molecular mechanisms, including enzyme kinetics, metabolic flux, and specific protein interactions, determine whether a given gene mutation is expressed as dominant or recessive.

THE MOLECULAR BASIS OF DOMINANCE
1981 · cited by 789
This foundational study demonstrates that dominance and phenotypic effects emerge from systemic properties, enzyme kinetics, and metabolic fluxes rather than being intrinsic, isolated properties of the genes themselves.

DOMINANCE RELATIONSHIPS BETWEEN TWO ALLELIC GENES CONTROLLING GLYCOSYLTRANSFERASES WITH DIFFERENT SUBSTRATE SPECIFICITY IN MELANDRIUM
1974 · cited by 12
This paper shows that dominance between allelic variants can be determined by biochemical parameters such as differences in Vmax and enzyme kinetics rather than transcriptional control.
