What is an example of transient polymorphism?
Transient polymorphism can be seen in a population when there are two alleles present in a gene pool. One of the two alternate forms of the allele is progressively replaced by another allele during inheritance. This happens due to strong environmental pressure to eliminate one allele from the gene pool.
What are examples of polymorphisms?
The most common example is sexual dimorphism, which occurs in many organisms. Other examples are mimetic forms of butterflies (see mimicry), and human hemoglobin and blood types. According to the theory of evolution, polymorphism results from evolutionary processes, as does any aspect of a species.
What are examples of balanced polymorphism?
Sickle Cell disease is an autosomal recessive disorder that causes anemia, joint pain, a swollen spleen, and frequent, severe infections. It illustrates balanced polymorphism because carriers are resistant to malaria, an infection by the parasite Plasmodium falciparum that causes cycles of chills and fever.
What is polymorphism short answer?
answer Polymorphism is the ability of an object to take on many forms. The most common use of polymorphism in OOP occurs when a parent class reference is used to refer to a child class object.Any Java object that can pass more than one IS-A test is considered to be polymorphic.
What does polymorphic mean in biology?
Polymorphism = Polymorphism involves one of two or more variants of a particular DNA sequence. The most common type of polymorphism involves variation at a single base pair. Polymorphisms can also be much larger in size and involve long stretches of DNA.
What is polymorphism in animals?
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. A discontinuous genetic variation divides the individuals of a population into two or more sharply distinct forms.
What causes polymorphism?
polymorphism can be maintained by a balance between variation created by new mutations and natural selection (see mutational load). genetic variation may be caused by frequency-dependent selection. multiple niche polymorphism exists when different genotypes should have different fitnesses in different niches.
What is Human polymorphism?
What is inversion polymorphism?
Inversion polymorphisms occur when a large inverted region of a chromosome segregates within populations with its non-inverted (‘standard’) counterpart.
What is polymorphism Wikipedia?
From Wikipedia, the free encyclopedia. In biology, polymorphism is the occurrence of two or more clearly different forms or phenotypes in a population of a species. Different types of polymorphism have been identified and are listed separately.
