Polymorphism is a phenomenon that includes the presence of the more distinctive phenotypes or morphs inside one species. Humans have three distinctly different phenotypes and morphs inside one species. The black panther of big cats represents the classic polymorphism. Different morphs of polymorphic species occur at the same time and occupy the same role as other healthy individuals.
Polymorphism is a consequence of evolution, and it inherits from one generation to the next. The development of natural selection modifies the scope of inheritance for polymorphism. Inheritance is the passing on of traits to the offspring from a parental generation. However, inheritance has been a very universally used term in many areas, including computer science, law taxation, and many other social and cultural facets.
In terms of sexual reproduction, only the gametes with robust character traits can pass through their offspring population. Everything about biology is designed to promote the best possible genetic inheritance. Evolution through natural selection also takes place to flourish the best-inherited individuals.
