7. After graduation, you and 19 of your closest friends (lets say 10 males and 10 females) charter a plane to go on a round-the-world tour. Unfortunately, you all crash land (safely) on a deserted island. No one finds you and you start a new population totally isolated from the rest of the world. Two of your friends carry (i.e. are heterozygous for) the recessive cystic fibrosis allele (c). Assuming that the frequency of this allele does not change as the population grows, what will be the incidence of cystic fibrosis on your island? .

6. The gene for curled wings (C/c) is located nearly at the end of the long arm of chromosome 2 of Drosophila, while the gene for smooth abdomen (S/s) is nearly at the end of the short arm of the same chromosome (the centromere is located about 2/3 of the distance along the chromosome). The gene for ebony body (E/e) is near the end of chromosome 3. A true-breeding wild type fly is crossed with a true-breeding fly that has curled wings, smooth abdomen and ebony body (all recessive traits). (a) Write the genotypes of the parents and the offspring (F1). (b) Sketch the arrangement of chromosomes 2 and 3 at metaphase of meiosis 1 in the gamete-producing cells of the F1. (Assume no crossing-over). (c) Sketch all possible combinations of the two chromosomes in the gametes. (Assume no crossing-over). (d) If the F1 is crossed with a triple recessive fly (known as a backcross), what would be the phenotypes of the progeny (assume no crossing-over). What would you expect their relative numbers to be? (e) If crossing-over occurred what difference would you expect in the results of the F1 backcross? .

6. It is Halloween evening and Nick and Rachel have just returned home after trick-or-treating. They have been dividing up the candy and are now down to four candy bars: Snickers, Milky Way, Kit Kat, and Baby Ruth. The allocation procedure is that Nick gets to choose one of the four candy bars, then Rachel can choose one of the three remaining candy bars, then Nick chooses one of the two remaining candy bars, and finally Rachel gets the remaining candy bar. Nick's preferences are that he most likes Snickers (assigning it a payoff of 5) then Milky Way (payoff of 4), then Kit Kat (payoff of 3), and lastly Baby Ruth (payoff of 1). Rachel most likes Milky Way (payoff of 6), then Kit Kat (payoff of 5), then Baby Ruth (payoff of 4), and finally Snickers (payoff of 2). Using SPNE, how are the candy bars allocated between Nick and Rachel? .
