Plan to spend about 1 hour on the following exercises

  • Someone tells you that he repeated Mende's experiment with green/yellow peas and in 987 peas counted 738 were yellow and 249 were green.
    1. Do these results agree with Mendel?
    2. What is probability of such a match?
    3. What is your general conclusion?
  • Repeat the exercise assuming that on total, 100 peas were evaluated and the distribution was 77:23
  • Frequency of a mutant allele is 0.01. What should be sample size to have at least 10 carriers with probability
    1. 50%
    2. 95%
    3. 99%
