5. You are studying the MN blood group in a small village population in Borneo and want to know if the population is in HardyâWeinberg (HW) equilibrium. MN blood type is due to a single-gene locus segregating the two co-dominant M and N blood type alleles (LM, LN). The following are sample data from this population: Phenotypes M MN N Total # genotypes 287 665 123 1075 A. Calculate the genotypic frequencies. (3 points) B. Calculate frequencies for the LM and LN alleles. (2 points) â C. Use a ï£2 analysis and determine whether this population is in H-W equilibrium.

| 18. | (Problem 28b) The human MN blood type is determined by two codominant alleles, LM and LN. The frequency of LM in Eskimos on a small Arctic island is 0.80. If the inbreeding coefficient for this population is 0.05, what are the expected frequencies of the M, MN, and N blood types on the island? | ||||||||||||||||||||||||

| N | NN | 160 | 0.16 |
A population sample of 1,000 individuals was made for the MN blood group. The genotypes are easily measured since the alleles are co-dominant individuals were blood typed and the results are shown in the figure. Assume the population is in equilibrium. The frequency of M allele in the population is ? _______________. The frequency of the N allele in the population is ? ________________ Now suppose that the population is mating randomly : The frequency of the MM x MM mating is ?______________ The frequency of the MM x MN mating is ? _____________The frequency of MM x NN mating is ? _______________ The frequency of the MN x MN mating is?___________ The frequency of the MN x NN mating is ? ______________The frequency of the NN x NN mating is ?_____________
