Imagine that you have a sample of 2 chromosomes in the 2 island model of population structure. Each island has a size 10,000 diploid individuals. Assume that m=0.005. Calculate: (a) The probability of a coalescent event occurring before a migration event if the 2 chromosomes are sampled from the same population. (b) The probability of a coalescent event occurring before a migration event if the 2 chromosomes are sampled from different populations. (c) The probability of a coalescent event occurring...

Page 1 Question 1 Suppose we take repeated random samples of size 20 from a population with a Select all that apply. mean of 60 and a standard deviation of 8. Which of the following statements is 10 points true about the sampling distribution of the sample mean (x)? Check all that apply. A. The distribution is normal regardless of the shape of the population distribution, because the sample size is large enough. B. The distribution will be normal as...
