- Of which postzygotic barrier is the mule an example?Perfect pitch is the ability to identify a note when it is sounded. In a study of this behavior, perfect pitch was found to predominate in females (24 out of 35 in one group). In one group of seven families, individuals in each family had perfect pitch. In two of those families, the affected individuals included a parent and a child. In another group of three families, three or more members (up to five) of each had perfect pitch, and in all three families, two generations were involved. Given this information, what, if any, conclusions can you draw about whether this behavioral trait might be genetic? How would you test your conclusion? What further evidence would be needed to confirm your conclusion?A scientific study demonstrated that rat mothering behavior impacts the stress response in their pups. Rats that were born and grew up with attentive mothers showed low activation of stress-response genes later in life, while rats with inattentive mothers had high activation of stress-response genes in the same situation. An additional study that swapped the pups at birth (i.e., rats born to inattentive mothers grew up with attentive mothers and vice versa) showed the same positive effect of attentive mothering. How do genetics and/or epigenetics explain the results of this study?
- The ABO blood groups in humans are expressed as the IA,IB and i alleles. The IAallele encodes the A blood group antigen, IB encodes B, and i encodes O. Both A and B are dominant to 0. If a heterozygous blood type A parent (IAi) and a heterozygous blood type B parent (IBi) mate, one quarter of their offspring are expected to have the AB blood type IAIBin which both arnigens are expressed equally. Therefore, ABO blood groups are an example of: a. multiple alleles and incomplete dominance b. codominance and incomplete dominance c. incomplete dominance only d. multiple alleles and codominanceName three genes whose mutations lead to an altered behavioral phenotype. Briefly describe the normal function of the mutated gene as well as the altered phenotype.Identify a possible advantage and a possible disadvantage of a genetic test that would identify genes in individuals that increase their probability of having Alzheimer’s disease later in life.
- Animal Models: The Search for Behavior Genes You are a researcher studying an autosomal dominant neurodegenerative disorder. You have cloned the gene underlying the disorder and have found that it encodes an enzyme that is overexpressed in the neurons of individuals who have the disorder. To better understand how this enzyme causes neurodegeneration in humans, you make a strain of transgenic Drosophila whose nerve cells overexpress the enzyme. a. How might you use these transgenic flies to try to gain insight into the disease or identify drugs that might be useful in the treatment of the disease? b. Can you think of any potential limitations of this approach?The sacrifice of the life of an individual so that the genes of relatives may be passed on is called ____ ___________ . operant learning kin selection kinesis imprintingEVOLUTION LINK What is the common ground between evolutionary biologists and developmental biologists who have adopted the perspective known as Evo Devo?
- Improving the nutritional value of food has long been one of the goals in agricultural genetics. Crossing different strains of plants and animals followed by generations of artificial selection have yielded some successes, including the development of high-protein maize. The use of gene transfer biotechnology has led to other advances, including the creation of nutritionally enhanced rice to combat vitamin A deficiency and blindness. Researchers are now turning their attention to the nutritional enhancement of animals that are used as food. Scientists are now turning their attention to using gene transfer technology to nutritionally enhance animal foods. Recently, biotechnology was used to produce a sheep with increased amounts of an omega-3 essential fatty acid that plays an important role in the development of the nervous system and, in adults, reduces the risk of coronary artery disease. Once a small number of transgenic animals have been produced, they can be bred by conventional methods to establish a source of nutritionally enhanced meat and milk. The use of biotechnology is presenting consumers with many new choices, which will become more common in the future. Increasingly, we will all have to educate ourselves about the pros and cons of such decisions. How would you explain your decision to eat nutritionally enhanced meat from animals modified by biotechnology?Improving the nutritional value of food has long been one of the goals in agricultural genetics.
