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:

• Geographic isolation refers to separation by physical barriers. But the question doesn't mention any such barriers.
• Reproductive isolation means inability to inter - breed. Here, the insects can inter - breed.
• Different species cannot inter - breed and produce fertile offspring. Since these insects can reproduce and produce offspring, they are not different species.
• The biological species concept states that a species is a group of organisms that can inter - breed and produce fertile offspring. Since the two insect groups can reproduce and produce offspring, they meet the criteria of being the same species.

Answer:

The insects are the same species.
