Parapatric Speciation Occurs When

question 49

Multiple Choice

Parapatric speciation occurs when

• A) selection causes a single species to develop different adaptations to a similar environment.
• B) a population is divided into two reproductively isolated subgroups that form separate species.
• C) a single species experiences a gradient of environmental differences within its geographic range, which result in reproductive isolation.
• D) a formerly isolated subpopulation recolonizes its home range and mates with the remaining individuals.

Definitions:

Current Path(s)

The route that electrical current flows through in a circuit, which may include components like resistors, capacitors, and inductors.

Total Resistance

The overall opposition to electric current flow in a series circuit, calculated by summing the resistance values of all components.

Series Circuits

Electrical circuits in which components are connected end-to-end, so that there is only one path for current flow.

Voltage Drop

The reduction in voltage in a part of a circuit due to resistance or impedance, seen in the difference in voltage across a component or conductor.
