A Short Treatise on Mutations
Primary Mutations: Simply put, the most drastic expression of a mutant's X-Gene: Charles Xavier's telepathy, Magneto's mastery of magnetism, Kitty Pryde's molecular phasing, the dramatic esoteric abilities defined by laymen as superpowers.
Ancillary Mutations: Defined as lesser, often solely cosmetic expressions of a mutant's X-Gene, most commonly physical deviations from human form or the odd pigmentation of skin and hair tissue (most commonly blue) though this classification is problematic for a number of reasons.
First off, what is to say that that the physical mutations are the primary, and any superpowers are side effects. There are also the cases where physical mutation is inextricably linked to the primary, as in the case of animalistic or bestial mutations, such as Mortimer Toynbee. And finally there are the cases where the odd physiological change is the only expression of the X-Gene.
A list of Commonly Seen Secondary Mutations:
Altered eyes, (Non-white sclera, unnaturally coloured irises, altered pupil shape, lack of visible irises)
Blue pigmentation of skin and hair.
"Unnatural" pigmentation of the hair (Most commonly white or blue via melanin mutation).
An abnormal number of fingers (Often varying from 4 to 6)
Extended lifespan and comparatively slow aging upon reaching physical maturity
Increased durability and ability to recover from injury, even if not related to their primary mutation.
Secondary Mutations: Mutations that develop after the initial X-Gene expression, usually developed as a response to extreme pressure situations. The most famous and dramatic example of a secondary mutation would be Emma Frost's living diamond form, developed in the wake of Mummudrai's assault on Genosha.
But once again, "secondary" mutation is a subjective term for the infinitely varied development of mutant powers. Is Bobby Drake's ability to transform into living ice a secondary mutation, or the natural progression of his cryokinetic abilities? Was Hank McCoy's constantly changing, blue furred form a natural development, or a response to attempted genetic therapy?
