Origin of Species

Question 1

Prezygotic Isolating

Answer 1

prevents zygote fertilization

Question 2

Prezygotic Isolation Mechanisms:

Answer 2

-Temporal
-Ecological
-Behavioral
-Mechanical

Question 3

Temporal Mechanism

Answer 3

occurs when two species mate at different times of year

Question 4

Ecological Mechanism

Answer 4

occurs when two species occupy different habitats

Question 5

Behavioral Mechanism

Answer 5

occurs when two species have different courtship behaviors

Question 6

Behavioral Mechanism

Answer 6

occurs when two species have different courtship behaviors

Question 7

Mechanical Mechanism

Answer 7

occurs when physical difference prevents copulation/pollunation from happening

Question 8

Postzygotic Isolating

Answer 8

keeps hybrid zygotes from developing into healthy, fertile adults

Question 8

Postzygotic Isolating

Answer 8

keeps hybrid zygotes from developing into healthy, fertile adults

Question 9

Postzygotic Isolation Mechanisms

Answer 9

-Hybrid Inviability
-Hybrid Infertility
-Hybrid Breakdown

Question 9

Postzygotic Isolation Mechanisms

Answer 9

-Hybrid Inviability
-Hybrid Infertility
-Hybrid Breakdown

Question 10

Hybrid Infertility Mechanism

Answer 10

hybrid fails to produce functional gametes

Question 11

Hubrid Inviability Mechanism

Answer 11

hybrids are produced but fail to develop to reproductive maturity

Question 12

Hybrid Breakdown Mechanism

Answer 12

F1 hybrids are fertile, but F2 generation fails to develop properly

Question 13

Speciation

Answer 13

the creation of a new species as organisms diverge from a common ancestor
