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 recent years, the country of Zambia in Africa has had increasing cases of malaria. If 8 % of the population is born with a severe form of sickle-cell anemia (ss), what percentage of the population will be more resistant to malaria because they are heterozygous (Ss) for the sickle-cell gene, under the Hardy-Weinberg assumption?
Do you think the allele for sickle cell anemia would be common in regions where malaria did not exist? Explain why or why not.
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 an interesting genetic disease. Normal homozygous individials (SS) have normal blood cells that are easily infected with the malarial parasite. Thus, many of these individuals become very ill from the parasite and many die. Individuals homozygous for the sickle-cell trait (ss) have red blood cells that readily collapse when deoxygenated. Although malaria cannot grow in these red blood cells, individuals often die because of this genetic defect causes deformation of red blood cells. However, individuals with the heterozygous condition (Ss) have some sickling of red blood cells, but generally not enough to cause mortality. In addition, malaria cannot survive well within these "partially defective" red blood cells. Thus, heterozygotes tend to survive better than either of the homozygous conditions. Assuming HWE, if 9% of an African population is born with a severe form of sickle-cell anemia (ss), what percentage of the population will be more resistant to malaria…

The most common allele of the β chain of hemoglobin in humans, ???,H⁢bA, has glutamic acid at the sixth position. Two different amino acid substitutions at the sixth position produce two variants, ???H⁢bS and ???,H⁢bC, of the sickle‑cell allele. The ???H⁢bS allele occurs when valine is substituted for glutamic acid, and the ???H⁢bC allele occurs when lysine is substituted for glutamic acid. To answer the question, refer to the amino acid table. Match the class of amino acid and the chemical property to each possible amino acid. Not all answers will be placed.
Tay-Sachs disease in humans is caused by a recessive allele. The disease is characterized by mental deficiency and blindness, with death occurring by 4 years of age. Among Ashkenazi Jews of central European ancestry, about 1 in 3600 children is born with the disease. Assume Hardy-Weinberg equilibrium and calculate the frequency of the Tay- Sachs allele in this population. Round your answer to the nearest 0.001. Type your answer...

Give typing answer with explanation and conclusion Approximately 1 out of every 10,000 Caucasians in the USA are born with the recessive disease cystic fibrosis. If this trait is in Hardy-Weinberg equilibrium, approximately how many people are carriers?
