Question 1

Which of the following best describes the concept of 'fitness' in evolutionary biology?

Accepted Answer

The number of offspring an individual produces that survive and reproduce

Question 2

According to Hardy-Weinberg equilibrium, what is the expected frequency of the heterozygote genotype in a population where $$p = 0.7$$ and $$q = 0.3$$?

Accepted Answer

$$2pq = 2(0.7)(0.3) = 0.42$$

Question 3

Which scientist is known as the 'father of paleontology' and proposed catastrophism?

Accepted Answer

Georges Cuvier

Question 4

Which of the following is an example of a homologous structure?

Accepted Answer

The wings of a bat and the arms of a human

Question 5

A population of beetles has the following genotype frequencies: $$AA = 0.36$$, $$Aa = 0.48$$, $$aa = 0.16. $$What are the allele frequencies for $$A$$ and $$a$$?

Accepted Answer

$$p = 0.6$$, $$q = 0.4$$

Question 6

Which of the following best describes allopatric speciation?

Accepted Answer

Speciation that occurs when populations are separated by a physical barrier

Question 7

Which of the following statements about artificial selection is correct?

Accepted Answer

It is a process where humans select for desirable traits in organisms

Question 8

Which of the following is NOT a requirement for Hardy-Weinberg equilibrium?

Accepted Answer

Natural selection

Question 9

Which taxonomic rank is immediately broader than 'Family'?

Accepted Answer

Order

Question 10

Which of the following best explains why analogous structures arise?

Accepted Answer

Convergent evolution due to similar environmental pressures

Question 11

A phylogenetic tree shows that two species share a recent common ancestor. What does this imply about their evolutionary relationship?

Accepted Answer

They are more closely related to each other than to species with a more distant ancestor

Question 12

Which of the following is an example of postzygotic reproductive isolation?

Accepted Answer

Hybrid offspring are sterile

Question 13

Which of the following best describes genetic drift?

Accepted Answer

Random changes in allele frequencies in small populations

Question 14

Which of the following is a correct example of binomial nomenclature?

Accepted Answer

Felis catus

Question 15

Which of the following scenarios best illustrates the founder effect?

Accepted Answer

A small group of individuals colonizes a new island, leading to different allele frequencies than the original population

Question 16

Which of the following is the correct order of taxonomic ranks from broadest to most specific?

Accepted Answer

Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species

Question 17

Which of the following best describes the biological species concept?

Accepted Answer

A group of populations whose members can interbreed and produce viable, fertile offspring

Question 18

Which of the following is an example of a prezygotic barrier?

Accepted Answer

Temporal isolation

Question 19

If the frequency of allele $$A is$$ $$p = 0.8$$ and allele $$a is$$ $$q = 0.2$$, what is the expected frequency of genotype $$aa$$ under Hardy-Weinberg equilibrium?

Accepted Answer

$$q^2$$ = $$(0.2)^2 = 0.04$

Question 20

Which of the following best describes the difference between microevolution and macroevolution?

Accepted Answer

Microevolution refers to changes in allele frequencies within a population, while macroevolution refers to broad patterns of evolutionary change above the species level
