A mutation in an of the recessive hemoglobin gene on chromosome 11 causes sickle-cell disease, but also confers malaria resistance. The allele frequency in African Americans is 14%. 1. What percent of the population have two copies of the gene and are therefore immune to malaria? 2. What percent of the population are less susceptible to malaria but do not have sickle-cell anemia since they are heterozygous?

Sickle cell anemia is caused by a recessive allele at a single gene. As we discussed in class, being a homozygote for the sickle cell allele is almost always lethal, but heterozygotes tend to be resistant against malaria although they have a mild form of anemia. Because of this heterozygote advantage, the allele for sickle cell anemia has a frequency of more than 10% in some human populations. How would present allele frequencies of the sickle cell allele change, if there was no heterozygote advantage or disadvantage (that is, that heterozygotes would be identical to ‘normal’ homozygotes – no malaria resistance, no anemia)? How would the change in sickle cell allele frequencies compare to scenario a (extirpation of malaria)
In a hypothetical population, 16% have sickle-cell anemia. The population is in Hardy-Weinberg equilibrium. ( sickle-cell anemia is recessive) What percentage of the population produces only normal hemoglobin? What percentage of the population is heterozygous?
Humans who are born homozygous for the recessive sickle cell allele die of sickle cell anemia, while those who are heterozygous are resistant to malaria. 5% of the population of the Congo are homozygous recessive for the sickle cell allele. What percentage of the population is resistant to malaria?
It has been hypothesized that people who are heterozygous for the allele that causes the deadly genetic condition cystic fibrosis (which, among other symptoms, reduces fertility) are more resistant to the deadly disease tuberculosis. Question - if the cystic fibrosis allel protects against tuberculosis the same what the sickle cell allele protects against malaria, then which of the following should be true in comparison between regions with or with out TB. -cystic fibrosis deaths should be more common in regions with tb - CYSTIic fibrosis deaths should be less common in regions with tb - CYSTIic fibrosis deaths should be equally common in regions with tb -Regional differences in the cystic fibrosis death rate should be purly random and upredictable.
In the genetics unit you learned that sickle cell anemia is an autosomal recessive condition. In 2016, assume in the City of Markham there are 1000 people out of 300000 people who have sickle cell anemia. Assume global warming continues for the next 50 years and in the year 2066 there are 20000 people out of 500000 in Markham who have sickle cell anemia. a)What are the allele frequencies in 2016? What are the allele frequencies in 2066? Is microevolution evident? b)Due to global warming, assume the numbers of malaria carrying mosquitoes in Markham dramatically increased between 2016 and 2066. What do you believe is the main cause of the microevolution in Markham? (Hint- refer to the 5 factors affecting microevolution and refer back…
If, within specific regional populations over two thousand years ago, sickle-cell anemia killed those individuals born with it before they could reproduce to pass it on to offspring, how did it persist in these populations? Group of answer choices A-Because of late-onset of the disease. B-Because it is cause by a virus and it spreads faster than people died. C-Because of the basic principles of mendelian inheritance that result in some heterozygote "carrier" combinations. D-Because malaria made it possible to survive sickle cell anemia since the parasite would carry oxygen on the blood cells with the mutated hemoglobin. E-It does not persist. Natural selection removes the allele because people die from both malaria and sickle-cell anemia.
Cystic fibrosis is a genetic disease caused by a recessive allele. Two parents without the disease have a child with the disease, indicating they are both heterozygotes. Assuming that the child did not have a mutation giving it the disease, what is the probability that a second child of the same parents would have the disease? Group of answer choices a. 1 b. 0.25 c. 0 d. 0.5
In humans, the genetic disease cystic fibrosis is caused by a recessive allele (a). The normal (healthy) allele is dominant (A). What is the genotype of someone who has cystic fibrosis? What are the two different genotypes that a healthy person could have? If two people were both heterozygous for the cystic fibrosis gene, what fraction of their children would be likely to have this disease? Hint: Draw a Punnett square to figure it out.
In Sweden 1/500 are born with an autosomal recessive disorder called thalassemia. What is the carrier frequency within the population?
In a hypothetical population, 16% have sickle-cell anemia. The population is in Hardy-Weinberg equilibrium. ( sickle-cell anemia is recessive) What is the frequency of the allele for sickle-cell anemia? What is the frequency of the allele for normal hemoglobin?
What is the selective factor, or selective environment, which allows carriers of the sickle-cell allele to have higher fitness than other genotypes? Group of answer choices A-Africa B-sickle-cell disease C-AIDS D-malaria
