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:

According to the biological species concept, a species is a group of organisms that can interbreed and produce fertile offspring. In this case, the two insect groups can reproduce and their offspring can also breed. Geographic isolation refers to a physical barrier separating populations, which is not indicated here. Reproductive isolation would prevent successful breeding (e.g., no offspring or infertile offspring). Since they can interbreed and have fertile offspring, they are not different species.

Answer:

The insects are the same species.
