Reproductive Isolating Mechanisms Flashcards
1
Q
Hybrid Inviability
A
sperm and egg combine successfully, but genetic information is insufficient/incompatible
2
Q
Behavioural Isolation
A
a complex courtship between males and females, a “call and response” before mating
3
Q
Ecological Isolation
A
two related species occupy different ecosystems
4
Q
Gametic Isolation
A
sperm and egg cell are chemically incompatible
5
Q
Mechanical Isolation
A
morphological differences between species
6
Q
Hybrid Breakdown
A
two species produce a hybrid , but the successive generations of that hybrid are weak with low viability
7
Q
Hybrid Sterility
A
a hybrid offspring survives well but is not capable of reproduction
8
Q
Temporal Isolation
A
two related species have different breeding seasons
