- The trait of blood pressure in humans has a frequency distributionthat is similar to a normal distribution. The following graph showsthe ranges of blood pressures for a selected population of people.The red line depicts the frequency distribution of the systolic pressuresfor the entire population. Several individuals with high bloodpressure were identified, and the blood pressures of their relativeswere determined. This frequency distribution is depicted with a blueline. (Note: The blue line does not include the people who wereidentified with high blood pressure; it includes only their relatives.) What do these data suggest with regard to a genetic basis for highblood pressure? What statistical approach could you use to determinethe heritability for this trait?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)?Should I try to rescue my sister who is drowning if there is a 75% chance that I will drown in the process? Assume that humans produce an average of 2 offspring in their lifetime. Remember that Hamilton’s rule is satisfied if rB>C. What is the value of C in this situation: What is the value of B in this situation: What is the value of r in this situation: Should I try to rescue my sibling? Yes or no
- The following frequencies were gathered in an African population affected with sickle-cell anemia: SS, 75.5%; Ss, 23.0%; ss, 1.5% (S = normal hemoglobin allele; s = mutant hemoglobin allele). Calculate the genotypic frequencies and determine whether this data represent a population that is in HWE.(i) State the Hardy-Weinberg principle.(ii) When there is a disturbance in the Hardy-Weinberg equilibrium, what would it result in?(iii) According to this principle, what is the sum total of all allelic frequencies?Heterozygotes at the sickle-cell locus produce both normal and abnormal sickle-cell hemoglobin. When hemoglobin molecules are packed into a heterozygote’s red blood cells, some cells receive relatively large quantities of abnormal hemoglobin, making these cells prone to sickling. Explain how these molecular and cellular events lead to emergent properties at the individual and population levels of biological organization.
- Cerebellar abiotrophy (CA) is a recessive, genetic neurological disease found in the Arabian horse breed. If the incidence of this disease is about 1 in 400 Arabian horses, estimate the frequency of carriers in a population in Hardy-Weinberg equilibrium.

What other considerations should be included in the discussion of the leadingcauses of deaths for these populations?You read a study in which 55 male participants (aged 55-70 years) were assessed for handgrip strength, and changes in cardiovascular health over a 2-year period.

Suppose that in a certain island population of 1000 individuals there are 250 individuals that have the genotype DD, 500 individuals that are heterozygotes, and 250 have the genotype dd.
