The M and N factors are glycoproteins that are found on the surface of red blood cells. Unlike other types of red blood cell antigens, The M and N factors do not cause antibody reactions in human blood transfusions. People with type M blood are homozygous for the M allele, and people with type N blood are homozygous for the N allele. Heterozygous individuals have type MN blood. In a study of population of Inuit living in the Northwest Territories, 512 people have blood type M, 256 had blood type MN, AND 32 has blood type N.
Now as for my questions...
A) Calculate the frequency of each allele, M and N , in the population studied.
B) WHat would be the expected frequency of each genotype in the next generation, assuming that this population is in genetic equilibrium for the trait.
C) In a second study group, the frequencies of the genotypes were 0.306 MM, 0.491 MN, AND 0.203 NN. Could this second study group have, in fact, come from the previously described Inuit population? Explain your answer...

One of my final questions and I just don't understand it! Any help would be greatly appreciated!
in studying a population of lizards, scientists sampled 47 sections of habitat, each section was 29km^2. it was found that the density of the lizards was 1/3.8km^2 a)calculate the size of the lizard population living in the area
so stuck on this question... if there is 1 lizard/3.8km, then would there be 7.63 per section?
Population density is population divided by total land area.
1 / 3.8 = x / 29
Solve for x and multiple by 47.
Question 4
1- Suppose that sample of beef broth initially contains 16 bacterial cells. After 4.0 h, there are 1.6 x 106 bacterial cells in the sample. Calculate the growth rate of the bacterial population for the given time interval. (Record your answer in scientific notation: x X 10n )
2- The Alberta greater sage grouse population was about 4375 in 1970. By 2002, the population was estimated to be only about 350 birds. Calculate the growth rate for the population from 1970 to 2002.
3- Between 1996 and 2001, Cochrane Alberta was the fastest growing municipality in Canada, with a per capita growth rate of 0.589. There were about 7424 people living in Cochrane in 1996. How many people lived there in 2001?
4- The experimentally re-introduced grey wolf population of Idaho was 310 at the beginning of 2004. Over the year, 112 pups were born and 49 individuals died or were removed from the study area. Calculate the per capita growth rate of this grey wolf population during the study period.

1. The winter food supply of buds from shurbs influences that stability of snowshoe hare populations. The available supply of "nutritious buds" is a/an a) density-independent limiting factor for snowshoe hare b) example of a climax species c) example of a community if pioneer species d) density-dependent limiting factor for snowshoe hare
2. In winter, snowshoe hares create pathways in the snow between feeding and resting sites. These travel lanes are then used by porcupines, making the porcupine's movement through deep snow easier. What relationship exists between the snowshoe hare and the porcupine? a) Mutualism b) Intraspecific competition c) Predator-prey d) Commensalism
3. Gause's "Principle of Competitive Exclusion" states that when two different populations occupy the same ecological niche, one of the populations will be eliminated. Both the mallard duck and pin-tail ducks occupy wetland areas. The mallard duck and the pin-tail duck can live in the same habitat because there is a) significant interspecific competition for food and breeding areas b) significant intraspecific competition for food and breeding areas c) little interspecific competition for food and breeding areas d) little intraspecific competition for food and breeding areas
4. Large fishing vessels called trawlers use nets that are dragged along the seabed and often have catastrophic effects on the sea floor habitat. Prohibiting commercial fishing by trawlers could save not only the targeted fish species, but also many other marine species. The recovery of the sea floor habitat after trawlers have been prohibited in a particular region is called a) primary succession b) pioneer succession c) climax succession d) secondary succession
1. The winter coat colour of the snowshoe hare makes it difficult to spot in winter. In the spring it sheds its coat for a brown coat that also provides camouflage. The name of this natural defense mechanism is known as
a. protective colouration b. Müllerian mimicry c. Batesian mimicry d. aposematic colouration
2. When an organism looks like a well-defended model to deter predators, but is defenseless itself, it has a form of mimicry known as
a. Batesian mimicry b. Müllerian mimicry c. Hershey and Chase mimincry d. Watson and Crick mimicry
3. Gause's "Principle of Competitive Exclusion" states that when two different populations occupy the same ecological niche, one of the populations will be eliminated. Both the mallard duck and pin-tail ducks occupy wetland areas. The mallard duck and the pin-tail duck can live in the same habitat because there is
a. significant interspecific competition for food and breeding areas b. little intraspecific competition for food and breeding areas c. little interspecfic competition for food and breeding areas d. significant intraspecific competition for food and breeding areas

Suppose that a population of 3 500 Zebra mussels occupied a rectangular territory 2.00 m by 2.00 m. Calculate the average density of the Zebra mussel population.
(Record your answer to three significant digits.)
Answer: _____ /m2
To answer this, you'll need to know the area in m^2. So, first multiple 2 and 2 together to get 4. Then, take the number of mussels and divide it by four. That's the number you put in the open slot.
