Relies on different characteristics among species

A

Morphology species concept

21
Q

The mode of speciation in which new organisms are formed on the outskirts of an environment and new niches are formed

A

Parapatric speciation

22
Q

The condition in which a mistake occurs during meiosis and doubles the number of chromosomes

A

Polyploidyism

23
Q

The term for periods of stability that are followed by quick bursts of changes in populations

A

Punctuated equilibrium

24
The mode of speciation in which two species day bridge from with in the same ecosystem
Reproductive isolation
25
The lack of gene flow that causes two distinct populations from one ancestral form
Speciation
26
The name for organisms that can interbreed and create fertile offspring
Species
27
The pattern of speciation that occurs very quickly because many variations are created when they move to new niche is it to avoid competition
Sympatric speciation
28
The mode of speciation in which a physical barrier causes divergence that can also be called geographic
Temporal
29
P plus Q equals one
Allele frequency
30
Spatial behavioral mechanical Temporel gamete incompatibility
Pre-zygotic reproductive isolation
31
Hybrid invisibility and Hybrid sterility
Post zygotic reproductive isolation
32
No mutation population is large mating is random no immigration or immigration genotype is suited for survival
Genetic equilibrium
33
Opposite of genetic equilibrium
Microevolution
34
P squared plus 2PQ plus Q squared equals one
Genotype frequencie
