As some of you may know, the X-Men series refers to mutants by different classifications of "levels". Below is a basic description of what each classification means.
ALPHA:
Alpha mutants have powerful, advantageous mutant traits and no disadvantageous flaws. Perhaps the most feared of mutants, alphas look completely human yet have some of the most powerful abilities recorded. Common belief is that Homo Superior will eventually be formed by all alphas, and therefore alphas are the epitome of mutantkind. Currently it is estimated less than 10% of all mutants are alphas, although given they look human the percentage might be somewhat greater.
BETA:
Betas are not weaker than alphas in what power regards, but they are not perfect. Along their advantageous mutations they have minor flaws, sometimes merely cosmetic, but that hinders them in some significant way. It is believed about 10% of all mutants are betas.
GAMMA:
Gammas are also powerful mutants, having some impressive gifts, but along with those powers they also have major flaws that make their lives hard, often miserable, and many times, shortened. Roughly 10% of all mutants are Gammas, and they are usually easy to recognize, as they are often saddled with important physical defects.
DELTA:
Delta mutants lack the impressive powers of alphas, but share their lack of flaws. Deltas are mutants with small abilities of little use under most circumstances. The number of deltas in the world is unknown, but it is assumed they are at least 50% of all mutants, and the number could be far greater because a good number of deltas do not even know they are mutants.
EPSILON:
Epsilons are the unfortunate ones among Homo Superiors. Epsilons often have minor superhuman traits, but those are overshadowed by crippling major flaws that makes a normal life for them almost completely impossible. It is believed about 20% of all mutants are epsilons, but often is very difficult to distinguish them from gammas.
OMEGA:
Omega mutants are those with the ultimate power, the baddest of the bad, the supermen of urban myth. 'Omega' is not a scientific classification for Homo Superior, but a popular label that is usually applied to powerful alphas whose powers seem limitless.
