Question

Speciation is not a precise division: overlap between closely related species can occur in areas called hybrid zones. Organisms may mate to produce _____________________with other similar organisms. The fitness of these hybrid offspring can affect the two species' evolutionary path. In hybrid _____________________, low hybrid fitness can_____________________ speciation. In hybrid _____________________, high hybrid fitness can delay or _____________________speciation. Scientists propose two models for the rate of speciation: the _____________________model illustrates how a species can change slowly over time. The _____________________model demonstrates how change can occur quickly from a parent generation to a new species.

Answer 1

Answer:

The emergence of new species from surviving ancestral species and both species continue to interact during a transition period is known as Sympatric Speciation.

Explanation:

Hybrid Zone is the  area where two species continue to interact. Hybrid offspring are produced by two different species.

1) hybrid offspring

2) zones

3) reinforces

4) zones

5) Slow down

6) gradual speciation model

7) punctuated equilibrium
