Origin: Formed within English, by derivation. Etymons: mutation n., -on suffix¹.

Etymology: < mut- (in mutation n.) + -on suffix¹. Compare recon n.²

Genetics.

The smallest element of genetic material that when altered can give rise to a mutation (usually identified as a single base pair). Cf. recon n.²

1970 E. J. Ambrose & D. M. Easty Cell Biol. x. 356 It seems probable that the smallest unit of recombination (the recon) has in fact the same dimensions as the smallest unit of mutation (the muton), that is a single nucleotide base pair in the DNA molecule.
