Textbook Question
Chapter 21, Problem 12TYK
Discuss Concepts Many human diseases are caused by recessive alleles that are not expressed in heterozygotes. Some people think that eugenics—the selective breeding of humans to eliminate undesirable genetic traits—provides a way for us to rid our populations of such harmful alleles. Explain why eugenics cannot eliminate such genetic traits from human populations.

Please check the attached picture and do only for "youth-earth creationistic" and "ontological reductionistic"arrow_forwardResearchers are very interested in studying identical twins separated at birth and raised apart. So far, data suggests that such twins are more alike than researchers predicted; they frequently have similar personalities, mannerisms, habits, and interests. What general questions do you think researchers hope to answer by studying such twins? Why do identical twins make good subjects for this research? What abuses might occur if the studies are not evaluated critically and if the results are carelessly cited to support a social agenda?arrow_forwardFrom your research, you discover that in this species of fish, the allele for black color is dominant to orange color. Based on this research, can you determine the genotype of a black fish just by looking at it? Why or why not? Yes, because the recessive allele must have been eliminated by the dominant one. Yes, because the phenotype always expresses all the alleles. No, because you do not know the DNA sequence. No, because it could be either homozygous dominant or heterozygous.arrow_forward
- Alzheimer's is believed to be caused by a dominant allele, however, it continues to persist in populations, even though it is deleterious. Explain why the allele for Alzheimer's persists using an evolutionary justification.arrow_forwardWhich of the following is true regarding understanding the results of genetic testing? A. If the test shows that you have the allele for a genetic disorder, you may be able to reduce your risk of developing that disorder with lifestyle changes. B. If the test shows that you have the allele for a genetic disorder, you will, eventually, show symptoms of that disorder. C. Because we know the functions of all the genes in the human genome, genetic tests can give you complete and accurate information regarding your medical health. D. If the test shows that you do not carry the allele for a particular disorder, there is no chance that you will get that disorder.arrow_forwardMAKE A simple sketch and label characteristics Choose a human-related organism to study. As you consider strategies to enhance the social value of this organism, think of other desirable attributes that may be added to it. Imagination is a powerful tool, so let it go wild and imagine that you can transfer genes across other animals. For example: A gene from a firefly has been transferred into tobacco plants so that they may glow in the dark, as demonstrated by geneticists. Tobacco pests are less likely to attack at night because of this.arrow_forward
- What is individual eugenics and why do some people think it is not true eugenics? (answer both questions directly and briefly)arrow_forwardThe drug tamoxifen has been used to treat some types of breast cancer. Suppose even among female patients with the same tumor grade there is variation in responsiveness to tamoxifen. It is also found that this variation is at least partly genetic; his variation is at least partly genetic; women with a relative who had a low responsiveness to the drug are at higher risk of low responsiveness to the drug The target of tamoxifen is a protein called the estrogen receptor. A. Outline how a “candidate gene approach” could be conducted to investigate whether variation in the gene for estrogen receptor affects tamoxifen responsivenessarrow_forwardAs energy is limited to organisms, females can interpret the production of large or bright badges or ornaments by males as a sign that they have enough energy/resources to produce those signals and still survive. This idea is predicted by the good genes hypothesis. True Falsearrow_forward
- Nancy Jones is a doctor who specializes in genetic diseases. For many years she has been studying populations of people who have Huntington’s disease. Dr. Jones has a special interest in Huntington’s disease because her mother died of this disease after many years living in a wheelchair. Dr. Jones’s father does not appear to have the disease. She has developed a test that can detect the dominant Huntington’s gene before symptoms appear and she has performed this test on many people. This test involves mapping a person’s genome to determine if the dominant Huntington’s gene is present. Dr. Jones is unsure if she should take the test herself as it will not prevent the disease from developing, only give the person advanced warning of the disease. Nancy Jones has a sister. Draw a pedigree chart that maps the disease through this family. Make sure to indicate those family members that have the disease, those that do not have the disease and those whose status is unknown. If you were Nancy…arrow_forwardWhich of the following statements about the theories of senescence is correct? Question 2 options: The reason why organisms become old and decrepit is because an individual would often have accumulated too much energy in its lifetime in the form of fat reserve; therefore, an older individual often dies from old-age related diseases. An allele that shows its deleterious effect later in life will always have a smaller impact on an organism's fitness than an allele that shows its deleterious effect early in life. Therefore, late-acting deleterious mutations can be fixed in the population, resulting in shortened lifespans. The allele that can result in early reproduction will always be selected for, even if it comes with a cost of earlier senescence. Typically, for species that live fast would usually die young. None of the abovearrow_forwardOrganizations that aim to protect the rights of animals have been battling leisure breeders to stop selective breeding because they view it as a form of abuse or cruelty to animals. Selective breeding or artificial selection is a mechanism that has brought a huge impact on the gene frequency of animals especially domesticated ones like dogs and cats. There are cases when breeding animals such as dogs resulted in diseases and malformation or abnormalities in the resulting offspring. Is s it proper to continue selective breeding?
