Gene Frequency

    One-thousand individuals were screened for their genotype at the MN blood group locus. The numbers of each genotype were:

MM 298
   

MN 489
   

NN 213

    Assuming random mating, calculate the gene frequency for the M allele and the expected genotype frequencies. Use the chi-squared test to determine that mating is random.

Since there are a 1000 individuals, the percent of 298 is 298 / 1000 = 29.8% are MM. Similarly, 489 / 1000 = 48.9 % are MN (Hybrids), and 213 / 1000 = 21.3% are NN.

Is this problem done? or do i need to also find the frequency for the M allele and how would i use the chi-squared test to determine that mating is random?
