One way to classify humans is by their blood type. There are over two dozen ways to group blood types. One of them is by the presence of the D antigen on the surface of blood cells. If an individual expresses the D antigen, they are referred to as Rh positive. This is controlled by an autosomal dominant allele. In a given town, 16% of the student population is considered Rh negative.
If this town's high school has 2,000 students, how many would you expect to be heterozygous for the D antigen?

A population of squirrels has 100 black individuals and 400 grey individuals.
What is the phenotype frequency of black squirrels?

Which of the following questions would best be tested using mathematical modeling?

In the late 1970's, the Galapagos Islands experienced a severe drought that sharply reduced the finch population living there. It was discovered that only finches with large, thick beaks survived the drought as they subsisted on cactus, which are drought tolerant plants.
In the early 1980's, the Galapagos Islands underwent an El Nino event that led to higher annual levels of precipitation than normal. This climate event occurred just a few years after the drought. The increase in rainfall led to a dramatic increase in growth of seed-producing plants, which led to an abundance of foods for seed-eating finches, which have small, short beaks.
The increase in rainfall also decreased the availability of cactuses on the islands. Which of the following would you predict occurred in the finch population as a result of the second change in climate? 

Find the mis-match from the following pairs.

Human earwax texture is determined by a single gene with two alleles, wet and dry. Dry is recessive and wet is dominant.
Evidence suggests that the dry allele first appeared in Eastern Asia about 2,000 generations ago. The frequency of the dry allele in a European population is .15. What percentage of this population is expected to have the wet earwax phenotype?

Examine the data showing the percent identity of the GAPDH gene and protein sequences between humans and the three species shown below.

Species	Gene Identity	Protein Identity
Chimpanzee	99.6%	100%
Fruit Fry	72.4%	76.7%
Roundworm	68.2%	74.3%

Provide a plausible reason for why the percent identity between gene sequences is lower than the percent identity of protein sequences.

In a particular population of mice that lives in the Southwestern United States, there are two fur color variants: black and light brown. The black fur is a dominant trait in these mice. The population described lives in an area dominated by dark-colored rock and that is populated by owls that prey upon mice that do not blend into the environment. The frequency of the black fur allele in this particular population is 0.6.
If the rock were to become covered by sand dunes, what change in the population would you predict?
