intergenetic

Pertaining to multiple genera.

interspecific and intergenetic hybridization

Of or pertaining to multiple genes.

My own intuition is that beneficial genetic mutations do not emerge merely as random errors in genetic copying but emerge inevitably when the optimum intergenetic and thermodynamic conditions

The characteristic diversity of the hypertrophic CMP phenotype is attributable to the intergenetic heterogeneity (with a variety of mutations encoding protein components of the cardiac sarcomere)

Pertaining to multiple languages with different roots.

Intra- and intergenetic language contact led to intermediate stages of simplification of the system (Luwo, Thuri) without necessarily involving fundamental typological changes.
