Q

Natural Selection

A

Influenced by the gene pool and its allelic frequency; when the allelic frequency is consistent for generations it is said to be in genetic equilibrium and not evolving

16
Q

Stabilizing selection

A

Favors average individuals in a population as the best fit to survive

17
Q

Directional selection

A

Favoring an extreme form of a trait

18
Q

Disruptive selection

A

Either of the two extremes are favored

19
Q

Speciation

A

Evolution of new species

20
Q

Geographies isolation

A

Occurs when a physical barrier separates a population into groups

21
Q

Behavioral isolation

A

Differences in courtship rituals or other behaviors prevent mating

22
Q

Temporal isolation

A

(Temporal = time) having multiple of a Normal set of chromosomes

23
Q

gradualism

A

Process of evolution at a slow steady rate with small, adaptive changes gradually accumulated over time

24
Q

Polyploidy

A

Having multiple of a normal set of chromosomes (can occur in one generation)

25
Divergent Evolution
Pattern of evolution in which species that once were all similar to the ancestral species become more and more distinct
26
Convergent evolution
Pattern of evolution in which distantly related organisms evolve similar traits
27
Why does evolution occur?
The changes in the gene pool (mutations, other)
