Molecular mechanisms, including enzyme kinetics, metabolic flux, and specific protein interactions, determine whether a given gene mutation is expressed as dominant or recessive.

The analysis

The retrieved papers provide strong biochemical and genetic evidence showing that dominance is governed by underlying molecular mechanisms such as enzyme kinetics, systemic metabolic flux, and specific gene targets, rather than being a purely abstract inheritance pattern.

THE MOLECULAR BASIS OF DOMINANCE

Recorded source metadata

Henrik Kacser, James A Burns. THE MOLECULAR BASIS OF DOMINANCE. 1981. https://doi.org/10.1093/genetics/97.3-4.639

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

Recorded source metadata

J van Brederode, G van Nigtevecht. DOMINANCE RELATIONSHIPS BETWEEN TWO ALLELIC GENES CONTROLLING GLYCOSYLTRANSFERASES WITH DIFFERENT SUBSTRATE SPECIFICITY IN MELANDRIUM. 1974. https://doi.org/10.1093/genetics/77.3.507

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.
