Requirements to learn these problems: I really need to learn the topic not just the answers. • Please provide: o 1 introductory paragraph; o supporting paragraphs (1 per each point); o 1 paragraph should be devoted to responding to alternative explanation o 1 concluding paragraph • Total: 4-5 short paragraphs or explained statements. 1. Question A: The diagram below (see Figure 2) is a human pedigree for a family that suffers from Duchenne muscular dystrophy (DMD). Explain why the unborn child has about a 1% chance of being afflicted. 2. Question B: The data in Table 1 below is from a drosophila cross between a triply heterozygous female (sc+, cw+, e+/sc, cw, e) and a homozygous recessive male (sc, cw, e/sc, cw, e). The map in Figure 3 shows a model of the gene order and arrangement in the female. Defend or refute the map (model) based on the data. If you refute the map, then suggest a map that is consistent with the data.
