Exam 27: Population Genetics

In a certain population, the frequency of allele A is 0.3 and the frequency of allele a is 0.7. The population inbreeds such that f = 0.1. What is the frequency of each genotype in the population?

The probability that a gene will be altered by a mutation is called the mutation rate.

Which of the following is not true concerning a population in equilibrium according to the Hardy-Weinberg rule?

The degree of relatedness of two members of a pedigree is calculated using ________.

Which of the following is true regarding a balanced polymorphism?

In a given population of Drosophila, curly wings (c) is recessive to the wild-type condition of straight wings (c+). You isolate a population of 35 curly winged flies, 70 flies that are heterozygous for straight wings and 45 that are homozygous for straight wings. What is the total number of alleles in the gene pool?

A group of individuals from the same species that occupy the same region and can interbreed with one another is the definition of a ________.

Mutations are the only source of genetic variation in a population.

New genetic variation in a population is a critical aspect of microevolution.

The allele pool is the sum of all of the alleles in a population.

The inbreeding coefficient (F) tells us what about an individual?

The measure of the reproductive success of a genotype is called Darwinian fitness.

The selection coefficient is the measure to which a phenotype is selected against.

In exon shuffling, the duplicated or rearranged exons appear as new domains in different genes.

Horizontal gene transfer between individuals in a population, while not a mutation, is a source of genetic variation.

In a given population of Drosophila, curly wings (c) is recessive to the wild-type condition of straight wings (c+). You isolate a population of 35 curly winged flies, 70 flies that are heterozygous for straight wings and 45 that are homozygous for straight wings. What is the frequency of alleles in this population?

Which type of selection would lead to two distinct phenotypes?

The accumulation of new mutations in a population is usually a ________ factor against the fitness of the population.

You are preparing to perform DNA fingerprinting by PCR for the first time. Select the reagent that would result in complications in the interpretation of your results.

If two individuals of a population, who vary in their phenotype, preferentially mate, it is called ________.
