Inheritance Vs. Polymorphism

Difference Between Inheritance And Polymorphism

The two concepts inheritance and polymorphism needs a careful study in order to differentiate between the two. In biology, polymorphism occurs when two or more distinctly different phenotypes are present in similar population of species. A neat illustration says that same habits should be witnessed in a morph at the very same time, and their mating sessions should be random. Polymorphism as a critical process has some relation with diverse concepts such as inheritance, biological diversity and adaptation.

Polymorphism is product development. It is the process of natural selection by which it is adapted. To know about point mutations in genotype molecular biologists used this term extensively.

The taxonomic nomenclature of zoology, the term “Morph” plus Latin name change added to the binomial or trinomial name. On the other hand, the idea of ​​morph botanical classification characterized by the terms “variety, sub variety” and “image”.

Polymorphism may be associated with a human life. Circumstances where it may occur include:

The human division of blood groups, particularly the ABO type is classified as genetic polymorphism

Glucose-6-phosphate dehydrogenase (G6PD) is a type of human polymorphism.

Cystic fibrosis, a defect that is congenital in nature affecting 1 in 2,000 humans, is caused by a mutated kind of gene called CF trans membrane regulator gene, CFTR.

Lactose tolerance/intolerance, which is the determining factor of one’s ability to metabolize lactose, is known dimorphism that has been associated to recent human evolution

On the other hand, the process of inheritance involves properties from a parent being passed on to her child even though the inherited properties have not undergone any particular defining through any kind of means. There are several properties being automatically inherited, and as the very word suggests, a child will be passed on these characteristics from the set of parents based on the properties they have.

Inheritance can be closely linked or related to subjects such as genetics and heredity. The passing of traits from the set of parents to their children is termed as heredity. In the heredity mechanism, variations can cause evolution based on the accumulated characteristics of individuals.


1 .A polymorphism occurs when two or more phenotypes have distinct variations (or less) in the similar group of species, but inheritance as a process involves transfer of assets from the parents to the off springs despite the fact that these properties are never properly stated.

2. Other polymorphisms may have little connection with such concepts like inheritance, biological diversity and integration, but inheritance relates itself with fields like heredity and genetics.
