Environmental factors can make it hard to understand how different genes work together to shape traits.

Challenges:

• The way genes interact can be tricky to see when everything is kept in a controlled setting.
• Different environments can cause traits to show up differently each time.
• It's tough to figure out how specific environmental influences affect genes when there is so much genetic noise.

Possible Solutions:

• Conduct controlled field experiments to keep things clear.
• Combine genetic mapping with studying the environment for better connections.

In the end, careful methods can help reduce these problems.
