If for a give population W Aa=1.0, what can you conclude?

• genotype Aa has that highest fitness of all genotypes

• genotype Aa has a fitness value that is 1% of that of the genotype with the highest fitness

• 100% of the individuals in the population have genotype Aa

• genotype Aa has 100% of the total fitness in the population

The term for a group of organisms that can interbreed and live in an isolated group

• species

• population

• community

• kingdom

If a gene has only one allele in a population this gene is said to be...

• monomorphic

• polymorphic

• mongenic

• polygenetic

The prevalence of the mutant allele for sickle cell anemia in populations exposed the malaria is an example of which of the following?

• Directional selection

• Balancing selection

• Disruptive selection

• Stabilizing selection

In the field of the population genetics and evolutionary biology what does the term "fitness" refers to?

• the ability to survive and reproduce

• the ability to use energy efficiency

• the ability to escape predators

• how well an organism is adapted to an environment

In the equation p2 +2pq +q2 = 1, what does the term q2 represent?

• The genotype frequency of homozygous recessive individuals

• genotype frequency of homozygous dominant individuals

• the genotype frequency of heterozygous individuals

• the fitness value of homozygous recessive individuals

If a population is at Hardy-Weinburg equilibrium for a particular gene, what does this mean?

• The population is not evolving

• the population is increasing in "fitness"

• the population is evolving

• the population is declining in numbers

If a small group of animals establishes a new population isolated from the original one, the genetic make-up of the new one is (instantly) likely to be different from the original one, as a result of:

• mutation

• gene flow

• genetic drift

• non-random mating

• natural selection

What is the value for the degrees of freedom in calculations for a correlation coefficient?

• (n-1)

• (n-1)/2

• (n-2)

• 2(n-1)

When analyzing two variables, the strength of the association between the variables is called the:

• covariance

• standard deviation

• correlation coefficient

• variance
