Q3. In a village, if the proportion of individuals who have sickle-cell disease is 0.40, and the population is assumed to be at Hardy-Weinberg equilibrium, what is the expected frequency of the HbS allele? (Hint: What is the genotype of people with sickle-cell disease, and how is that genotype represented in the Hardy-Weinberg equation?)

0.80 0.63 0.20 0.16

Answer #1

Hardy-Weinberg equation

In every question, it is important to realize what data has been provided. The data will fit to either of the equations and it is important step to understand where the data lies.

We have the proportion of individuals provided, therefore the data is the genotype frequency.

So for this equation -We are provided- HbSHbS2(q2)=0.40

Allele frequency-HbSHbS(q)==0.63

The allele frequency =0.63

Sickle cell disease (sickle cell anemia) is a relatively common disorder in individuals of African descent and affects approximately 1 in 500 African-Americans. Due to a mutation in an autosomal gene for hemoglobin, the homozygous recessive genotype leads to red blood cells that are relatively stiff and sticky, and deform into a sickle shape as they lose oxygen. This leads to problems in the spleen, and anemia. There are hundreds of different hemoglobin alleles. Individuals heterozygous for the sickle cell...

Group of answer choices a.) There is inbreeding in this population. b.) Ss genotypes have the highest fitness. c.) The population is in Hardy-Weinberg equilibrium. d.) SS genotypes...

Sickle-cell disease (SCD) is a type of blood disorder caused by a mutation in the HBB gene. The mutation results in the production of abnormal red blood cells; these sickle-shaped cells are unable to efficiently transport oxygen to body tissues. Individuals must inherit two abnormal copies of HBB in order to have SCD. Heterozygous individuals, with one normal copy of HBB and one abnormal copy, are said to have sickle-cell trait (SCT); they generally do not experience problems with their...

Sickle-cell anemia is an interesting genetic disease. Normal homozygous individuals (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 the genetic defect. However, individuals with the heterozygous condition (Ss) have some sickling...

Uniden’s condition is an X-linked recessive trait in the Redialer population. The trait allele F has a frequency of 0.005 in this population; that is. the frequency is the same in the male and female populations. Individuals with this trait have a strong desire to use land-line phones. Note, the trait gene is in Hardy Weinberg Equilibrium (HWE) for the female Redialer population. An man with the trait and an woman without the trait have a son. What is the...
