Genes and Their Evolution
- Another name for a reproductive population is
- The two main types of mutations are
- At the end of last semester, your professor had a baby. In class, she notes that her baby weighed 7.2 lbs at birth. The other babies in the nursery that week weighed 7.0 lbs, 6.8 lbs, 9.2 lbs, 7.5 lbs, and 7.3 lbs. When she asks what phenomenon this pattern of birth weights represents, you raise your hand and correctly answer
- The three patterns of natural selection are
- Mutation is the only source of new genetic material.
- Members of a population that can breed and produce viable offspring are considered to be of the same
- Which of the following abnormalities is not linked to malaria?
- The gene pool includes only the beneficial traits in a population.
- Huntington's chorea is a genetically linked debilitating degenerative disorder with an onset usually after the fourth decade of life. The reason that this disease has not been eliminated through natural selection and is actually quite prevalent among communities in Lake Maracaibo, Venezuela, is
- Your cousin just started a part-time job at a blood bank. He tells you that a surprisingly large number of Native Americans come in to donate blood. You explain to him that, based on what you learned in physical anthropology class, this is not all that surprising because
- Compared to the normal male karyotype, a man affected by Klinefelter's syndrome has
- A change in allele frequencies from one generation to the next is an example of evolution.
- If 70% of the hypothetical population passed along allele B, the dominant allele for brown eyes, and 30% passed along allele b, the recessive allele for blue eyes, the proportion of the subsequent generation with brown eyes would be ___________ given Hardy-Weinberg equilibrium.
- An online article that your professor asked you to critique states that African Americans cannot contract malaria, even if they go to endemic areas, because of a genetic trait that confers protection from the disease. Your response is that this article is incorrect because
- Populations in which reproduction within the group is encouraged are called
- Recent research indicates malaria was present in the Americas prior to Columbus.
- At Thanksgiving dinner, your dad tells the old story about how your great-grandmother's longevity was related to a daily breakfast of coffee and grapefruit plus broccoli every night with dinner. No one else in your extended family lived to over 100 like she did, and your dad insists that this is because everyone else in the family has failed in their attempt to follow her diet plan. You speak up this Thanksgiving and offer your hypothesis that the dietary failure of the subsequent generations suggests that
- The case of the peppered moth and industrial melanism during the Industrial Revolution in England illustrates
