6. (4 pts) 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. a. If random mating takes place in this population, what are the expected frequencies of the M, MN, and N blood types on the island? b. 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?

Step 1
We know the frequency of LM is 0.80. Since there are only two alleles, the frequency of LN must be 1 - 0.80 = 0.20. Show more…

Two codominant alleles, LM and LN, determine the human MN blood type. Suppose that the LM allele occurs with a frequency of 0.80 in a population of Eskimos on a small Arctic island. Match the expected frequencies to the M, MN, and N blood types in the population on the island for two mating scenarios: if random mating occurs, and if the inbreeding coefficient for this population is 0.05. mating scenario MM frequency MN frequency NN frequency random mating inbreeding coefficient of 0.05 Answer Bank 0.648 0.304 0.048 0.320 0.640 0.040

In a sample from an African population, the frequencies of the LM and LN alleles were 0.78 and 0.22, respectively. If the population mates randomly with respect to the M-N blood types, what are the expected frequencies of the M, MN, and N phenotypes?
