Biodiversity Flashcards
1
Q
Two reasons why populations might show very low levels of genetic diversity
A
Inbreeding
Population started with a small number of individuals (founder effect)
Genetic bottleneck
2
Q
Phylogeny
A
The evolutionary history/relationships of organisms
3
Q
Genetic bottleneck
A
An even that causes a big reduction in the population eg lots of them killed
This reduces genetic diversity
4
Q
Physiological adaptations
A
Processes inside an organisms body that increase its chance of survival eg bears in winter lower their rate of metabolism
