Three enzymes (F, G and H) convert colored intermediates to a final black product. Mutants for those enzymes accumulate the colored intermediates. From the data below, determine the order of intermediates and gene action in the pathway and then answer the questions below. F mutants accumulate white G mutants accumulate tan H mutants accumulate brown when F and H dihybrids are crossed with each other, they produce 9 black: 4 brown: 3 white when F and G dihybrids are crossed with each other, they produce 9 black: 4 white: 3 tan a) Which gene is furthest "upstream" in the pathway? Circle one: F G H b) Which gene is furthest "downstream" in the pathway? Circle one: F G H c) Which gene is responsible for making tan? Circle one: F G H d) What is the genotype of the tan progeny from the F and G dihybrid cross, with regard to the F, G and H genes?

3. From a function, f(x), we obtain the following data points: ($x_i$, f($x_i$)) = {(-0.5, e), (0, 1), (0.5, $e^{-1}$)}. (a) (5 marks) Using the Newton/Divided-Difference method, find the interpolating polynomial for f(x) using the data points above, and using it evaluate the approximate value of f(0.25). (b) (3+2 marks) State Cauchy's Theorem (Do not need to prove). Now suppose a function f(x) is five times differentiable, and it is interpolated by a degree five polynomial. Explain or state what would be the interpolation error.

3. A manager of the duty-free cosmetics shop at Heathrow Airport has given you a list of the items they sell and their sales figures. The manager (a marketing expert) is a bit confused by the revenue figures of certain items. She has noticed that when she offered a discount on 'powder', customers purchased 'foundation' as well. When she removed the discount on a known brand of 'foundation', customers bought 'foundation' of another brand. At the same time, when she removed the discount on a 'clinical foundation' (used in the treatment of facial spots) revenue increased. She has further noticed that passengers with first class boarding passes buy more of the known brand 'foundation' as compared to passengers with premium class boarding passes who buy more high quality 'foundation' than the economy class passengers. She knows you took economics at University; she is hoping all this will make sense to you. Given your understanding of elasticity, can you help the manager understand the situation and give her specific recommendations to help increase her revenues?
