Which are the mechanisms that prevent interbreeding between two different species whose ranges overlap?

A) Allopatric isolating mechanisms
B) Sympatric isolating mechanisms
C) Equilibrium isolating mechanisms
D) Preadaptive isolating mechanisms
E) Reproductive isolating mechanisms

Reproductive Isolating Mechanisms

The reproductive barriers that prevent a species from interbreeding with another species; as a result, each species’ gene pool is isolated from those of other species. See prezygotic barrier and postzygotic barrier.

Sympatric Isolating Mechanisms

Sympatric isolating mechanisms are barriers to breeding that occur when two species share the same habitat but develop behaviors or characteristics that prevent them from interbreeding.

Allopatric Isolating Mechanisms

Biological barriers that prevent species from interbreeding and producing fertile offspring when they are geographically separated.

  • Familiarize oneself with the multiple forms of reproductive isolation mechanisms and what they entail.
  • Differentiate between prezygotic and postzygotic mechanisms and their significance in the evolution of new species.
