- Which 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_forwardEnvironmental factors can influence the gene expression in some organisms. a. Describe how environmental factors can affect an organism's phenotype. b. Explain how light exposure can affect gene expression in organisms of the same species. Provide an example.arrow_forwardLet's consider a paternally imprinted gene. A female skink inherited alleles that that confer: 1) a mutant violet tail-color in the egg and 2) a mutant violet tail-color allele in the sperm. A male skink mate inherited a wild-type blue allele from the sperm and a mutant violet allele from the egg. They have 500 offspring. a. What tail color phenotypes do the parent male and parent female skinks have? Briefly explain your reasoning. female = male = b. What fraction of the offspring do you expect to have each phenotype (blue and violet tail color)? Briefly explain your reasoning/show your work.arrow_forward

They are polka-dotted! You decide to sequence samples from the polka-dot babies to find the mutation that caused this novel phenotype. What kind of genetics is this? a. Reverse Genetics b. Epigenetics c. Forward Genetics d. Genomics e. None of the abovearrow_forward
- Most of the genetic information we will get from our genome will not be hard evidence that we will or we won’t get a disease but is rather only probabilistic evidence. a. What does this mean? b. Why might knowing a single gene not tell you if you will get a particular condition?arrow_forwardFigure 3 shows the karyotypes of two individuals suffering from a genetic disorder. a) Name the genetic disorder for individuals A and B. b) Give three characteristics of individual B. c) What is the gender of individual A?arrow_forwardHow would the process of the double holiday junction model differ if identical DNA molecules were used in place of homologous ones? A.) Crossing over would NEVER be observed B.) No change the entire process would be the same C.) Gene conversion would never occur D.)

- Consider the first category of test-cross offspring shown in figure 8.2 (+b, LS). Consider also that the parents of the heterozygous female flies in the test cross had the following genotypes: bb, SS, and +, LL. A. What would be the physical phenotype of these flies? B. If PCR was conducted with the DNA of one of these flies using the primers for the molecular marker, what would be the appearance of the bands on an electrophoresis gel with the PCR products? C. If the gene for black body and the locus for the molecular marker (L long or S short) were unlinked, what proportion of the test-cross progeny would be black flies that are heterozygous for the molecular marker? What proportion would be flies with normal body color, which are homozygous for one form of the molecular marker? D. If the gene for black body and the locus for the molecular marker were linked, how would the proportion of flies be different?arrow_forwardA paper hypothesizes that white flowers are unable to produce anthocyanins (purple pigments) because they lack a functional “A” protein. However, it is also possible that an unknown gene is responsible for the lack of anthocyanins. Now that they have isolated DNA sequences of the “A” allele, design an experiment to use these DNA sequences to distinguish between these two hypotheses.arrow_forwardWhich of the following scenarios best describes an epistatic gene? Select one: a. Fur pattern is controlled by two genes such that one gene inhibits the expression of the other gene. b. Chicken combs follow a dominance hierarchy whereby a walnut comb is the most dominant and a single comb is the least dominant. c. Individuals with sickle cell anemia and carriers of the sickle cell allele have some resistance to malaria. d. Mouse fur colours are expressed as a blend of the dominant black colour and the recessive white colour, resulting in a heterozygous brown colour.arrow_forward
