Question

two insect groups vary genetically by two genes. when put together, they were able to reproduce and produce offspring that could also breed. which best describes this insect population?
the insects experienced geographic isolation.
the insects experienced reproductive isolation.
the insects are different species.
the insects are the same species.

Explanation:

To determine the correct answer, we analyze the options based on the definition of a species (organisms that can interbreed and produce fertile offspring).

• Geographic isolation involves physical separation (not relevant here as they were put together).
• Reproductive isolation means they can't interbreed (contradicted by them producing breeding offspring).
• Different species can't produce fertile offspring (ruled out).
• Since they interbred and produced fertile offspring, they are the same species.

Answer:

D. The insects are the same species.
