Definitions for "Polymorphic"
genes that have several alleles in a species, resulting in a wide variety of genotypes
occurrence together of two or more distinct morphological forms of a species.
presence in a population of two or more relatively common forms of a gene, chromosome, or genetically determined trait.
Ability to mutate by changing code segments to look different from one infection to another. This type of virus is a challenge for ant-virus detection methods.
A virus that attempts to evade detection by changing its internal structure or its encryption techniques. Polymorphic viruses change their "form" with each infection in order to avoid detection by antiviral software that scans for signature "forms". Less sophisticated systems are referred to as self-encrypting.
based on the self-encryption technique, a virus encrypts its code in a different manner each time it infects (its signature changes each time). Through polymorphism, however, the virus also encrypts the routine or algorithm it uses to encode its signature. This means that the virus can create variants of itself that are completely different from one infection to another. To detect these complex viruses, antivirus programs use decryption simulation techniques.
Having an irregular shape or various shapes. This term often describes microcalcifications which can indicate ductal carcinoma in situ (DCIS), an early stage breast cancer.
A polymorphic eruption means the lesions may have varied shapes.
an individual panel that repeats entities in different stages of an action
