Yvonne has one copy of a gene for an X-linked dominant disease. She is fortunate to have a very mild form of the disease, which suggests that in the relevant organs, the X chromosome containing the dominant disease allele is silenced by X inactivation. If she has children with a man who does not have this allele, what will be true about her future children? Check All That Apply Her daughters will definitely get the disease allele. Her sons will definitely get the disease allele. Her children will all have a 50% chance of inheriting the dominant disease allele. Her daughters will also have a mild form of the disease because X inactivation will occur in a similar pattern between mother and daughter.

Texts: 1- You are considering investing $1,000 in a T-bill that pays 0.05 and a risky portfolio, P, constructed with two risky securities, X and Y. The weights of X and Y in P are 0.60 and 0.40, respectively. X has an expected rate of return of 0.14 and variance of 0.01, and Y has an expected rate of return of 0.10 and a variance of 0.0081. The dollar value of your positions in X, Y, and the T-bills, respectively, if you decide to hold a portfolio that has an expected outcome of $1,120, is $108; $514; $378. True or False? 2- In a return-standard deviation space, which of the following statements is (are) true for risk-averse investors? I) An investor's own indifference curves might intersect. II) Indifference curves have negative slopes. III) In a set of indifference curves, the highest offers the greatest utility. IV) Indifference curves of two investors might intersect. 3- You manage a risky portfolio with an expected rate of return of 17% and a standard deviation of 37%. The T-bill rate is 5%. Your client chooses to invest 80% of a portfolio in your fund and 20% in a T-bill money market fund. Based on that, your client's Sharpe ratio is around 32%. True or False? 4- A reward-to-volatility ratio is useful in measuring the standard deviation per unit of expected returns. True or False?

With a vertical demand curve and an upward-sloping supply curve, we can predict that a. the price faced by consumers is 12 after the tax. b. the price faced by consumers is 8 after the tax. c. the price faced by consumers is 10 after the tax. d. the price faced by consumers is 11 after the tax. 6. Which of the following will most likely lead to a more equal distribution of income? a. more regressive national sales tax b. more progressive income taxes c. an increase in the high school dropout rate d. an increase in earnings for owners of capital 7. A 5-percent retail sales tax on all consumers purchases in a state is imposed. The sales tax is: a. a flat-rate tax b. a regressive tax c. a progressive tax d. either A or B 8. When a tax system is progressive, the marginal tax rate a. equals the average tax rate. b. is greater than c. is less than d. There is no relationship between the marginal and average tax rates under a progressive tax system.
