Question

Question asked by Filo student

Problem 8 (6pts) Two fruit flies mate with one another, one whose phenotype is sepia eyes (a recessive trait coded for by allele w) and an ebony body (recessive trait coded for by allele b), and the other whose phenotype is wild type for both eye color and body color. If you know the second fly is homozygous dominant for both traits... a. What is/are the potential genotype(s), and b. Phenotypes of their offspring? Answer and work: Problem 9 (8pts) Consider the F1 generation produced by the two fruit flies in Problem 8. Perform a dihybrid cross to produce the F2 generation offspring. a. What would the phenotypic ratio be of the F2 offspring? b. How about the genotypic ratio of the F2 offspring?

After reading the paragraph below, answer the questions that follow HPV is an infection that is normally fought by the human immune system, but it can lead to cancer in some individuals.While we already know that HPV vaccines help prevent HPV-related cancer, researchers are unsure as to what level of antibody concentration a person needs in order to be protected from HPV-related cancers. Scientists hypothesize that higher anti-HPV antibody levels may provide greater protection from HPV-related support this hypothesis. Suppose you design a study to test this hypothesis.Your study participants are adults determine if the study participants have an HPV-related cancer, and you also measure the concentration of anti-HPV antibodies in their blood. Answer the following question regarding this study. From the following choices, select the groups of individuals who would make the best participants for the control group in your study. a group of 100 vaccinated adult males and a group of 100 vaccinated adult females a group of 100 unvaccinated adult males and a group of 100 vaccinated adult males a group of 50 vaccinated adult males and a group of 150 vaccinated adult females a group of 100 unvaccinated adult males and a group of 100 unvaccinated adult females

As discussed in the lecture, maternal-fetal conflict occurs when natural selection for fetal gene expression and maternal gene expression oppose one another. Examples of maternal-fetal conflict arise particularly during nutritional acquisition. A similar phenomenon plays out in fetal cells during development, wherein some genes are maternally expressed and some paternally expressed—a phenomenon known as "genomic imprinting". Expression of these genes from the correct parent is critical for the development of the fetus, and expression of a chromosomal region from the wrong parent may result in one of several developmental disorders in humans. A) Is genomic imprinting expected to evolve more readily in species with: - Monogamous mating (species in which mating benefits both sexes relatively equally) - Non-monogamous mating (species in which mating benefits one sex more than the other) B) Consider a situation in which the maternal copy of a gene is normally expressed, but for some reason, the paternal copy is instead expressed in the developing fetus. Would we expect the following phenotypes to increase or decrease in this situation? (You can indicate your answer by circling, highlighting, or anything that makes it clear.) - Increase / Decrease. Infant birth weight - Increase / Decrease. Insulin production in the mother - Increase / Decrease. Size/invasiveness of placenta
