Question

Have the student use the infomration obtain regarding the USA population to determine the “Expected” frequency and counts as well as having them  to analyze the data and provide phenotype, genotype and allele frequencies plus the perform chi-square analyses. Have the student to complete every single empty square. For frequencies, (O-E)2
/E and x^2 round to two decimal places. Use whole numbers for counts… people are counted in whole numbers!
