Evolution 7.1 - 7.5 Quiz

Which islands did Charles Darwin visit that greatly influenced his theory of natural selection?

• Galapagos Islands

• Caribbean Islands

• Hawaiian Islands

• Falkland Islands

Which of the following best describes natural selection?

• The process by which individuals with beneficial traits produce more offspring

• The random change in allele frequency in a population

• The transfer of alleles from one population to another

• The principle that allele frequencies in a population will not change

What is genetic drift?

• A mechanism of evolution that occurs due to chance events

• A process that ensures genetic diversity within a population

• The movement of genes from one population to another

• A concept that describes the sexual preferences of individuals

Sexual selection can lead to the evolution of:

• Reduced genetic diversity

• Increased survival rates for both sexes

• Traits that improve mating success

• Equal sex ratios in offspring

Gene flow refers to:

• The transfer of alleles or genes from one population to another

• The random change in allele frequency in a population

• The process by which individuals with beneficial traits produce more offspring

• The principle that allele frequencies in a population will not change unless evolutionary forces act upon the population

Which of the following is a mechanism of evolution?

• Genetic Drift

• Gene Flow

• Natural Selection

• All of the above

Darwin's theory of evolution by natural selection was revolutionary because it:

• Disproved the idea of genetic inheritance

• Suggested that species are immutable

• Proposed a mechanism by which species could change over time

• Confirmed the prevailing belief that Earth was only a few thousand years old

In population genetics, genetic drift has a more significant effect in:

• Large populations

• Small populations

• Populations with high mutation rates

• Populations with high gene flow

• The principle of natural selection

• The Hardy-Weinberg equilibrium for two alleles

• The formula for calculating genetic drift

• The rate of gene flow between populations

Which of the following factors does NOT cause evolution to occur?

• Mutation

• Natural Selection

• Random Mating

• Genetic Drift
