Genetic markers have to be easily identifiable, associated with a specific locus, and highly polymorphic, because homozygotes do not provide any information.

The underlying genes responsible for defensin production are highly polymorphic.

The species can be difficult to identify because they are highly polymorphic and because they readily hybridize with each other.

Caltha palustris is a highly polymorphic species, showing continuous and independent variation in many features.

Many currently recognized species with very wide geographic ranges are highly polymorphic.

Using five such highly polymorphic markers, 24 cultivated genotypes could be differentiated (data not showed).

Changes or repeats in the hypervariable region are highly polymorphic.

The tree is perennial and highly polymorphic.

The highly polymorphic nature of many P. falciparum proteins results in significant challenges to vaccine design.

This is a highly polymorphic species for which four main color-pattern types have been described:
