What is balanced polymorphism?
A genetic polymorphism that is stable and is maintained in a population by natural selection, because the heterozygotes for particular alleles have a higher adaptive value (i.e. fitness) than either homozygote. From: balanced polymorphism in A Dictionary of Ecology »
What is balanced polymorphism in a population likely the result of?
balanced polymorphism A genetic polymorphism that is stable and is maintained in a population by natural selection, because the heterozygotes for particular alleles have a higher adaptive value (i.e. fitness) than either homozygote.
Which of the following is an example 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 a polymorphism quizlet?
polymorphism. having multiple forms of one thing. in inheritance it is done by function overloading. when both base and derived class have member functions with same declaration but different definitions.
What is balancing selection in biology?
Balancing selection occurs when multiple alleles are maintained in a population, which can result in their preservation over long evolutionary time periods. A characteristic signature of this long-term balancing selection is an excess number of intermediate frequency polymorphisms near the balanced variant.
Which of the following illnesses is a classic example of a balanced polymorphism maintained by heterozygous advantage?
A classic case of balanced polymorphism in human populations is sickle cell anemia.
Which of the following is an example of a balanced polymorphism maintained by heterozygous advantage?
Heterotic balance (heterozygous advantage) polymorphisms develop when the fitness of heterozygotes is higher than the fitness of both homozygotes in a given population. A classic case of balanced polymorphism in human populations is sickle cell anemia.
Which of the following is an example of both heterozygote advantage and balanced polymorphism?
Sickle cell anemia is the best-known example of heterozygote advantage and balanced polymorphism in humans.
What is the definition of polymorphism quizlet 9.5 2?
What is the definition of polymorphism? Polymorphism lets a method do different things depending on the type of the object it is called on.
What is a polymorphic reference?
A polymorphic reference is a variable that can refer to different types of objects at different points in time. It is typically compatible with the class that it refers to. For example, in the following case: Employee employee; The ’employee’ is a reference variable that may refer to an instance of the Employee class.
What is Human polymorphism?
​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.
