You were initially tasked with surveying the Gribell Island population to estimate the frequency of the white allele from the phenotype frequencies on the island. You identified 66 unique bears (let's assume they were uniquely tagged somehow), of which 16 bears were white. 6) What is the frequency (q) of the recessive allele based on the phenotypic data? 7) What would be the expected proportion and number of carriers of the recessive allele and those homozygous black and white? You then got some funding for your project to use molecular genetics to determine the genotypes of the 66 bears at the mc1r locus. What is the probability that the observed genotype numbers (Table 1) would deviate from the expected numbers (Q6 and 7) as much or more by chance? (assume a = 0.05) Report 1) the chi-square test statistic, 2) whether the result is significant or not, 3) a statement interpreting the outcome of your statistical test.
