Polymorphism Common

(genetics) the genetic variation within a population that natural selection can operate on

"The researchers discovered high levels of polymorphism in the gene pool, which provided the raw material for evolution to adapt the species to changing environments."

(chemistry) the existence of different kinds of crystal of the same chemical compound

"Geologists discovered that a single mineral could exist in multiple crystalline forms depending on the temperature and pressure conditions deep within the Earth's crust."

(biology) the existence of two or more forms of individuals within the same animal species (independent of sex differences)

"The discovery of polymorphism in these lizards revealed that both green and brown color variants existed within the single population, regardless of whether they were male or female."

The ability to assume different forms or shapes.

"The chameleon's skin shifts colors as a form of polymorphism, allowing it to blend seamlessly into its surroundings."
