Question: Assume that for a trait that is determined by a set of two alleles, the observed frequency for homozygous dominant, homozygous recessive, and heterozygous are 0.64, 0.26, and 0.1, respectively for a certain population. Calculate the frequency of p, the dominant allele, and then perform a chi-squared test with an alpha-value of 0.05 to test if the population is in Hardy-Weinberg equilibrium with a random sample of 1000 individuals.
