Question 2

Biological Species Concept

Answer 2

Defines “specie” as a population who’s members can produce fertile offspring with each other, but cannot do the same with members from a another species.

Question 3

Ecological Species Concept

Answer 3

Defines “specie” depending on the resources a population typically uses.

Answer 6

Impediments that hinder cross breeding between different species.

Question 7

Habitat Isolation

Answer 7

Possible mates do not meet due to living in different habitats.

Question 8

Behavioral Isolation

Answer 8

Possible mates can’t communicate due to different mating signs.

Question 9

Temporal Isolation

Answer 9

Possible mates cannot mate due to different mating time periods.

Question 10

Mechanical Isolation

Answer 10

Possible mates cannot mate due to different structurally built reproductive organs.

Question 11

Gametic Isolation

Answer 11

Possible mates cannot mate due to lack of fusion of gametes.

Question 12

Geographical Isolation

Answer 12

Possible mates never meet due to specific biomes.

Question 13

Postzygotic Barriers

Answer 13
