Speciation 1

Question 1

Biological Species Concept

Answer 1

This defines species as groups of actually or potentially interbreeding natural populations that are reproductively isolated from other such groups

Question 2

Temporal isolation

Answer 2

Mating or flowering at different seasons or at different times of the day

Question 3

Behavioral isolation

Answer 3

Species have different mating rituals

Question 4

Ecological isolation

Answer 4

Species utilize different resources in the habitat

Question 5

Mechanical isolation

Answer 5

Structural differences prevent mating or pollen transfer.

Question 6

Geographic isolation

Answer 6

species occur in different places

Question 7

prevention of gamete fusion

Answer 7

structural differences prevent mating or pollen transfer

Question 8

Hybrid Inviability

Answer 8

Prevents interbreeding between populations when their hybrids die young or are unable to reproduce

Question 9

adult hybrids can not reproduce due to mating behaviors that are a mixture of two parents

Answer 9

Hybrid Inviability

Question 10

Bishop and Monterey pines will interbreed in the lab but not in nature due to differing pollination times

Answer 10

Temporal Isolation

Question 11

What are the three steps after fertilization in Postzygotic Isolation Mechanisms that offspring have to go through?

Answer 11

Bad development, don’t survive in nature (SOTF), sterile or reduced fertility

Question 12

Means that alleles do not move between the gene pools of different species

Answer 12

Independent evolution
