How is the sickle allele maintained through natural selection?
Heterozygous individuals pass the dominant and recessive alleles to offspring.
How is the sickle-celled allele maintained through natural selection?
Individuals with two recessive alleles have very high rates of reproduction.
How is the sickle cell allele maintained through natural selection?
Individuals with two recessive alleles have very high rates of reproduction.
How is sickle cell alleles maintained through natural selection?
Heterozygous induviduals pass the dominant and recessive alleles to offspring
People with one sickle cell allele are not likely to get a malaria what is this an example of?
It is an example of Natural Selection, Modern Theories of Evolution.
Why are not Americans affected with sickle cell anaemia?
natural selection and heredity Americans are affected with sickle cell anaemia which mostly affects black people.
How does balancing selection affect the sickle cell allele in central Africa?
The sickle cell allele can be maintained in the central African population, above the frequency of gene mutation (balancing selection), because the heterozygous sickle cell individuals have an advantage in lifespan, in this malaria stricken region, over the homozygous alternatives. Homozygous sickle-sickle individuals die early from the sickle cell disease. Homozygous nonsickle-nonsickle die early from malaria. The heterozygous sickle-nonsickle have a higher survival against malaria and therefore the sickle cell allele is balanced selected.
Why would natural selection act against people with sickle cell anaemia in Europe?
because people in europe have not gotten used to sickle cell anemia because it is soo rare in europe
How natural selection means there is more sickle cell anemia in Africa?
Sickle cell anemia is more prevalent in Africa due to natural selection's role in conferring a survival advantage against malaria. The sickle cell trait (carrying one copy of the gene) provides some protection against the disease, allowing individuals with the trait to survive and reproduce more successfully in malaria-endemic regions. As a result, the frequency of the sickle cell allele increases in these populations, leading to higher rates of sickle cell anemia. This illustrates how environmental pressures can shape genetic traits within a population.
Examples of natural selection?
poop juju beans pickle heads are the most common but there are also some rare examples like lamas eating walnuts and doing a dance on a Saturday night.
Do primates have sickle cell anemia?
That is very interesting question, indeed. Your concern for the primates needs appreciation. The answer to this question is probably positive. Sickle cell anaemia is a natural selection in malaria endemic zone. The sickle cell trait patient is genetically resistant to malarial fever. So many primates suffer from malarial fever. From this finding you can say that sickle cell anaemia should be present in primates, who live in tropical countries.
What allele is responsible for maintaining sickle cell hemoglobin in African populations?
Balanced Selection
