What is a balanced polymorphism quizlet?
What is a balanced polymorphism quizlet?
Balanced polymorphism is an occurrence where different phenotypes are maintained at relatively stable frequencies in the population. Sickle-cell anemia is a result from a change in the hemoglobin molecule structure.
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 » Subjects: Science and technology — Life Sciences.
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.
Under what conditions would you expect to observe a balanced polymorphism?
Under what conditions would you expect to observe a balanced polymorphism? When natural selection favors the heterozygote.
Which of the following is a correct statement about fossils?
Which of the following are correct statements about fossils? Correct Answer(s): Fossils are the remains of once-living organisms, wholly or partially transformed into rock. The most common types of mammal fossils are bones and teeth.
What happens balance polymorphism?
n. A system of genes in which two alleles are maintained in stable equilibrium because the heterozygote is more fit than either of the homozygotes.
What is an example of genetic polymorphism?
All the types of blood groups are the example of genetic polymorphism, such as the ABO blood group system. We see this system having more than two morphs: A, B, AB, and O are the variants present in the entire human population, but these groups vary in proportion in different parts of the world.
Which of the following is a violation of the Hardy-Weinberg equilibrium?
One of the violations of Hardy-Weinberg equilibrium is selective mating. If birds prefer to mate with others that are similarly colored, then Hardy-Weinberg equilibrium is violated and the gene pool in the population is changing.
