question

The frequency of the gene for sickle-cell anemia in American Blacks is less than that found in the people living in their ancestral home in Africa. What factors might account for this difference?

category

biology

options

  1. The factors include improved healthcare in America that helps manage sickle-cell anemia, the death of individuals with homozygous sickle-cell genotype, and similar rates of interracial marriages in Africa and America.
  2. The factors include the introduction of a sickle-cell cure in America, the survival of individuals with homozygous sickle-cell genotype, and the presence of malaria in Africa.
  3. The factors include the presence of malaria in both America and Africa, the survival of individuals with the sickle-cell trait, and high levels of interracial marriages in both regions.
  4. The factors include selective migration patterns of African people with lower sickle-cell gene frequency to America, the survival advantage of sickle-cell trait carriers in malaria-endemic areas, and the genetic mixing due to interracial marriages in America.
  5. The factors include the presence of malaria in Africa, the survival of individuals with homozygous sickle-cell genotype, and lack of interracial marriages in America.
  6. The factors include the absence of malaria in America, the death of individuals with homozygous sickle-cell genotype, and interracial marriages in America diluting the sickle-cell genes.
  7. The factors include the presence of malaria in America, the survival of individuals with homozygous sickle-cell genotype, and lack of interracial marriages in Africa.
  8. The factors include the absence of malaria in both regions, the death of individuals with homozygous sickle-cell genotype in Africa, and the promotion of interracial marriages in America.
  9. The factors include the absence of malaria in Africa, the death of individuals with homozygous sickle-cell genotype, and interracial marriages in Africa diluting the sickle-cell genes.
  10. The factors include a higher rate of genetic mutations in America, the survival of individuals with the sickle-cell trait, and the absence of interracial marriages in Africa.
