In a large, randomly mating population, the frequency of the allele (s)for sickle-cell hemoglobin is 0.028. The results of studies have shownthat people with the following genotypes at the beta-chain locus producethe following average numbers of offspring:Genotype                       Average numberof offspring                                                    producedSS                                                     5Ss                                                      6ss                                                      0a. What will the frequency of the sickle-cell allele (s) be in the nextgeneration?b. What will the frequency of the sickle-cell allele be at equilibrium?

Based on the information shown in the chart above, what is the most likely inheritance pattern for the 'forked bristles' trait? why?

Suppose we define the Alzheimer’s disease phenotype as being diagnosed with the disease by age 75 years. In the human population, there are three alleles of the ApoE gene: ε2, ε3, ε4. They form an allelic series such that: 70% of 75 year olds with the ε4/ ε4 genotype have the Alzheimer’s phenotype 60% of 75 year olds with the ε3/ ε4 genotype have the Alzheimer’s phenotype 40% of 75 year olds with the ε3/ ε3 genotype have the Alzheimer’s phenotype 30% of 75 year olds with the ε2/ ε4 genotype have the Alzheimer’s phenotype 10% of 75 year olds with the ε2/ ε3 genotype have the Alzheimer’s phenotype If I have the ε4/ ε4 genotype and my wife has the ε2/ ε3 genotype, what is the probability that our child will have Alzheimer’s by age 75. Explain your reasoning

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.

A given autosomal locus has three possible alleles (A1, A2, and A3). Assuming that the numbers of individuals with the six possible genotypes are as follows, what would be the frequency of the A1 allele in the population?   A1A1 = 30 A1A2  = 27 A2A2 = 12 A1A3 = 17 A2A3   = 10 A3A3 = 4 What would be the frequency of the A1A2 genotype? Assume the population is under Hardy-Weinberg equilibrium.   A. 0.03   B. 0.107   C. 0.27   D. 0.317   E. 0.09   F. 0.182

Despite their excellent hygienic practices, the Kelatavicla lab experiences a devastating bacterial infection in their mouse population in 2012. Given the conditions in column B, predict what will happen to the frequency of the R allele over the years (increase, decrease, or remain the same) if the outbreak is not contained?

If 16% of an African population is born with a severe form of sickle-cell anemia (ss) due to a recessive allele s. what percentage of the population will be heterozygous (Ss) for the sickle-cell gene?

In humans, people with at least one dominant RhD allele have a Rh positive blood type. People with a homozygous recessive genotype have a Rh negative blood type. In the United States, 85% of the population is Rh positive and 15% are Rh negative. What are the values of p and q for the population in the United States (assuming that the American population is at Hardy-Weinberg equilibrium)?

Sickle cell anemia is a genetic disease most common in those of African ancestry that results from the mutation of a single basepair. This mutation results in a change to the hemoglobin protein. In this experiment, “S” will represent the normal allele and “s” thesickle allele. They are codominant alleles. Therefore, SS is normal, Ss is not fatal but mildly symptomatic, and ss is debilitating,painful, and often fatal. After hundreds or even thousands of generations, both alleles are still common in those of African ancestry. How would you explain this?
