The S-s antigen system in humans is controlled by twoco-dominant alleles, S and s.
In a group of 3146 individuals the following genotypic frequencieswere found: 188 SS,
717 Ss, 2241 ss.
A) Calculate the frequency of the S and s alleles.
B) Test whether the genotypic frequencies conform to theHardy-Weinberg
distribution using the Chi-square test.
C) A third allele is sometimes found at the S locus. The allele suis recessive to
both the S and s alleles, and can only be detected in thehomozygous state. If the
frequencies of the alleles S, s, and su are p, q, and rrespectively, what would be the
expected frequencies of the phenotypes S_, Ss, s_, susu? **Youranswers will be
equations written in terms of p, q and r.

On 2/15/2015, a 3-year forward contract, expiring 2/15/2018, ona non-dividend-paying stock was entered into when the stock pricewas $135 and the risk-free interest rate was 9.1% per annum withcontinuous compounding. 1 year later, on 2/15/2016, the stock pricebecomes $146. What is the "delivery" price of the forward contractentered into on 2/15/2015?

1. An asset manager anticipates the receipt of funds in 200days, which he will use to purchase a particular stock. The stock he had in mind is currently selling for P62.50 and will pay a P0.755 dividend in 50 days and another P0.75 dividend in 140 days. The risk free rate is 4.2%. The manager decides to commit to a future purchase of stock by going long a forward contract on the stock.
   REQUIRED:
   At what price would the manager commit to purchase the stock in 200 days through a forward contract?          (5 marks)
   Suppose the manager enters into the contract at the price you found in Part a. Now, 75 days later, the stock price is P55.75. Determine the value of the forward contract at this point.                       (5 marks)
   It is now the expiration day, and the stock price is P58.50. Determine the value of the forward contract at this time.         (5 marks)
