Question 1

What type of speciation occurs when a population becomes geographically isolated?

Accepted Answer

Allopatric speciation

Answer

Sympatric speciation

Answer

Parapatric speciation

Answer

Peripatric speciation

Question 2

Which of the following describes sympatric speciation?

Accepted Answer

Speciation that occurs without geographic separation

Answer

Speciation that occurs in small isolated populations

Answer

Speciation due to physical barriers

Answer

Speciation driven by environmental changes

Question 3

What is the primary mechanism that drives allopatric speciation?

Accepted Answer

Geographic isolation

Answer

Natural selection

Answer

Mutualism

Answer

Genetic drift

Question 4

Which process may lead to speciation through changes in mating behavior?

Accepted Answer

Behavioral isolation

Answer

Temporal isolation

Answer

Ecological isolation

Answer

Mechanical isolation

Question 5

What is the term for speciation that occurs when populations are separated by a physical barrier and then evolve independently?

Accepted Answer

Allopatric speciation

Answer

Adaptive radiation

Answer

Convergent evolution

Answer

Sympatric speciation

Question 6

What role does polyploidy play in speciation?

Accepted Answer

It can lead to the formation of new species, particularly in plants

Answer

It decreases the likelihood of mutations

Answer

It makes all individuals in a population identical

Answer

It increases genetic diversity within a population

Question 7

What is the effect of genetic drift on small populations during speciation?

Accepted Answer

It can lead to significant genetic changes and potentially speciation

Answer

It has no effect on small populations

Answer

It reduces genetic variation leading to extinction

Answer

It always results in increased fitness

Question 8

What is adaptive radiation?

Accepted Answer

The rapid evolution of diversely adapted species from a common ancestor

Answer

The extinction of species due to environmental changes

Answer

The gradual evolution of a single species into another

Answer

The hybridization of two distinct species

Question 9

What type of isolation occurs when two species breed at different times?

Accepted Answer

Temporal isolation

Answer

Behavioral isolation

Answer

Habitat isolation

Answer

Mechanical isolation

Question 10

Which of the following is a potential outcome of hybrid speciation?

Accepted Answer

Formation of a new species from the combination of two parent species

Answer

Complete reproduction failure of hybrids

Answer

Extinction of both parent species

Answer

Reinforcement of existing species boundaries
