Polymorphism (biology) - Wikipedia
In biology, polymorphism[1] is the occurrence of two or more clearly different morphs or forms, also referred to as alternative phenotypes, in the population of a species. To be classified as such, morphs must occupy the same habitat at the same time and belong to a panmictic population (one with random mating). [2]

3 天之前 · Polymorphism, as related to genomics, refers to the presence of two or more variant forms of a specific DNA sequence that can occur among different individuals or populations. The most common type of polymorphism involves variation at a single nucleotide (also called a single-nucleotide polymorphism, or SNP).
Polymorphism | Definition, Examples, & Facts | Britannica
Polymorphism, in biology, a discontinuous genetic variation resulting in the occurrence of several different forms or types of individuals among the members of a single species. The most obvious example of this is the separation of most higher organisms into male and female sexes.
多态性 (生物学) - 维基百科，自由的百科全书
多态性（英語： polymorphism ）在生物学中是指一个物种的同一种群中存在两种或多种明显不同的表型。多态性必须同一时间在同一栖息地中出现。 多态性必须同一时间在同一栖息地中出现。

2022年1月13日 · What is meant by polymorphism in biology? In simplest terms, polymorphism is a process where two or more possibilities of a trait are found on one gene. One example of polymorphism can be observed in jaguars. This species has more than one trait in its skin coloring. You must have seen jaguars with dark spots or light spots.

2022年5月15日 · A polymorphism is a genetic variant that appears in at least 1% of a population. (e.g., the human ABO blood groups, the human Rh factor, and the human major histocompatibility complex). By setting the cutoff at 1%, it excludes spontaneous mutations that may have occurred in - and spread through the descendants of - a single family.
Gene polymorphism - Wikipedia
Polymorphisms are classified based on what happens at the level of the individual mutation in the DNA sequence (or RNA sequence in the case of RNA viruses), and what effect the mutation has on the phenotype (i.e. silent or resulting in some change in function or change in fitness).

2021年2月19日 · Polymorphism in biology refers to the discontinuous genetic variations leading to the existence of two or more forms, stages, or phenotypes existing in the same species within the same population.
Polymorphisms - BioNinja
A polymorphism is the occurrence of two or more clearly different phenotypes within the same population of a species. Transient Polymorphisms. Occurs when there are two alleles in the gene pool and one allele is gradually replacing the other.
Polymorphism (biology) - bionity.com
Polymorphism in biology occurs when two or more clearly different types exist in the same population of the same species — in other words, the occurrence of more than one form or morph. The caste system in ants is an example.
