polymorphism

For the most part I think people are familiar with what scientists call SNPs, single nucleotide polymorphisms, and what other people might refer to as mutations.

So we conducted a genetic investigation that looked for single-nucleotide polymorphisms, or “snips”—differences in a single DNA building block between one plant and another.

We now understand the process by which a polymorphic race maintains its polymorphism.

Four days later, after the fourth ecdysis, the dimorphism becomes a polymorphism.

On these grounds I designate the phenomenon as polymorphism, although it may not yet have reached, as such, its sharpest limits.

It is chiefly amongst the microscopic species that polymorphism has been determined.

This system of reproduction is again noticed more in detail in the chapter on polymorphism.
