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?

Fan egg cell containing the (n+1) number of chromosomes combines with a sperm cell containing the (n) number of chromosomes, what is the result of this union? a) all future somatic cells of the organism will contain the (2n + 1) number of chromosomes. b) all future somatic cells of the organism will contain the (2n - 1) number of chromosomes. c) only certain somatic cells of the organism will contain the (2n + 1) number of chromosomes. d) all future somatic cells of the organism will contain the normal diploid number of chromosomes.

Sea levels are rising due to climate change while increasing numbers of people are moving into coastal areas. to accommodate more people, there has been increased construction of beachfront resorts and condominiums. how is this impacting sea turtle numbers and biodiversity and why? a. the increased human population in coastal areas has meant that more food is available to the turtles (e.g., dropped food, waste from restaurants), which has led to an increase in the numbers and diversity of sea turtles. b. there has been very little change in the numbers and biodiversity of sea turtles because the planet is so vast that they can simply relocate to less crowded beaches. c. this has resulted in a decrease in numbers and diversity of sea turtles because it is restricting available nesting sites, and hence reproduction. d. this has resulted in an increase in numbers and diversity of sea turtles because people are around to protect them from natural predators.
