The human MN blood group is determined by two codominant alleles, M and N. The following data were obtained from various human populations:

Percentages*
Population Place MM MN NN
Inuit East Greenland 83.5 15.6 0.9
Navajo Indians New Mexico 84.5 14.4 1.1
Finns Karajala 45.7 43.1 11.2
Russians Moscow 39.9 44.0 16.1
Aborigines Queensland 2.4 30.4 67.2

a. Calculate the allele frequencies in these five populations.
b. Which populations appear to be in Hardy-Weinberg equilibrium?

What is the significance of the protein-lined pits? a. protein attracts other proteins needed for atp synthesis within the cell. b. protein-lined pits are able to transport one molecule at a time down the concentration gradient within the cell. c. the polarity of proteins allows other polar molecules to attach and be transported in the cell by transport channels. d. receptors within the pits allow ligands to fuse and be transported into the cell by endocytosis.
