Resource summary

Question 1

Question
By definition evolution is:
Answer
  • Changes in allele and genotype frequencies in a population
  • Phenotypic variation in a population
  • Inbreeding with relatives
  • Adaptation of a population to neutral environments

Question 2

Question
Evolution acts at the level of the
Answer
  • community
  • species
  • population
  • ecosystem
  • individual

Question 3

Question
Which statement most accurately describes the process of natural selection?
Answer
  • Heritable traits that promote reproduction become more frequent in a population over time.
  • Only the strongest survive.
  • Survival of the fittest.
  • Organisms change by random chance over time.
  • The strong eliminate the weak in the race for survival.

Question 4

Question
Which of the following agents of evolutionary change results in adaptation?
Answer
  • natural selection
  • gene flow
  • genetic drift
  • all of these

Question 5

Question
All traits present in nature are a result of evolution due to natural selection.
Answer
  • True
  • False

Question 6

Question
Movement of individuals into a population can result in evolution.
Answer
  • True
  • False

Question 7

Question
Natural selection is a completely random process.
Answer
  • True
  • False

Question 8

Question
In the Hardy-Weinberg equation, p + q = 1, p and q represent
Answer
  • Frequency of genotypes in the population
  • Specific combination of alleles in an individual
  • All of these
  • Frequency of alleles of a single gene

Question 9

Question
Which of the following represents the frequency of heterozygotes in a population that is in Hardy-Weinberg equilibrium?
Answer
  • p
  • 2pq
  • q
  • q2
  • p2

Question 10

Question
Hardy-Weinberg equilibrium will not occur in a population in which:
Answer
  • Mutations do not occur
  • Individuals mate at random
  • Natural selection does not occur
  • Individuals immigrate or emigrate
  • Sexual selection does not occur

Question 11

Question
Which statement is NOT true about the maintenance of variation in a population?
Answer
  • Only phenotypes are acted on by selection, so heterozygotes serve as a reservoir of recessive alleles that may be adaptive in a different environment.
  • Variations allow for the presence of conditions such as sickle cell anemia.
  • Selection for adaptation to a particular environment ensures that the population will become stronger and more viable under all conditions.
  • Heterozygote advantages may lead to selection for the heterozygote above either homozygote.

Question 12

Question
Species that evolved more recently will be more advanced and better than their ancestral forms.
Answer
  • True
  • False

Question 13

Question
Fossil and genetic evidence strongly support the idea that modern humans
Answer
  • independently arose from three different ancestral Homo species in Africa and Eurasia.
  • derive from Neanderthals that independently evolved the features of modern humans in Europe and Africa.
  • all derive from a single African lineage that spread from there into other parts of the world.
  • derive from a hybridization of several African and Eurasian Homo species.

Question 14

Question
High concentrations of melanin resulting in darker skin reduces vitamin D production in regions of low UV.
Answer
  • True
  • False

Question 15

Question
UV light is used to produce vitamin D, however excessive amounts degrade folate, an essential vitamin. People whose ancestors lived in the tropics have darker skin because:
Answer
  • dark skin protected vitamin D from degradation
  • dark skin provides protection from folate degradation
  • dark skin allowed increased production of vitamin D
  • dark skin was important for social interactions
  • dark skin keeps people warmer

Question 16

Question
Scientists use genetics to trace the evolution and migration of humans. How do scientists know which populations are older than others?
Answer
  • Members of older populations have identical mitochondrial genomes.
  • Members of older populations have more genetic variability.
  • Members of older populations have more nuclear genes.
  • Members of older populations have more genes in their mitochondrial genomes.
  • Members of older populations have fewer nuclear genes.

Question 17

Question
What is the name for the differences between individuals?
Answer
  • Variation
  • Mutation
  • Genes

Question 19

Question
