Evolution Vocab Quiz

If genetic variation in a population remains constant, from one generation to the next, in the absence of disturbing factors, this population has reached...

• Modern Synthesis

• Population Variation

• Hardy Weinberg Equilibrium

• an Inbreeding Depression

Which of these is not a requirement of the Hardy Weinberg Equilibrium?

• No mutation

• Random Mating

• No Gene Flow

• Natural Selection

Northern elephant seals have reduced genetic variation probably due to the effects humans inflicted on them in the 1890s. Hunting reduced their population size to as few as 20 individuals at the end of the 19th century. What evolutionary concept is displayed in this example?

• Bottleneck Effect

• Founder Effect

• Directional Selection

• Frequency Dependent Selection

Microevolution is occurring whenever there is a change in ______ ______ in a population over generations.

• Adaptive Evolution

• Allele Frequency

• Genetic Structure

• Stabilizing Selection

Based off the data in the graph, which type of selection is occurring?

• Disruptive

• Stabilizing

• Directional

• Adaptive

Which type of evolutionary concept is being observed?

• Good Genes Hypothesis

• Frequency Dependent Selection

• Bottleneck

• Founder Effect

The Mexican long-nosed bat roosts in Big Bend National Park in West TX. They feed on nectar and pollen and hover while they feed. Additionally, its tongue can extend up to eight centimeters. The features of Mexican long-nosed bats are evidence of natural selection because their featrues are adaptations that ---

• lead to an increase in predation by other species of animals

• show that most DNA mutations are necessary and advantageous but do not increase reproductive success

• help individuals outcompete other individuals for food resources to increase survival and reproductive success

• are the result of intentional breeding

A selection that favors phenotypes that are either common or rare. Which type of selection best expresses the observed phenotype if a harmless kingsnake mimics the venomous coral snake?

• Frequency Dependent Selection

• Evolutionary Fitness

• Gene Flow

• Handicap Principle

MULTIPLE ANSWERS: Which two responses best describe a change in allele frequency due to migration and chance events like natural disasters?

• Selective Pressure

• Gene Flow

• Stabilizing Selection

• Genetic Drift

What is the term used to describe all of the alleles carried by all of the individuals in the population?
