Specifically, where would larvae be more commonly found? Or, does it depend on the particular dragonfly species? A reliable source would be helpful, but an informed general answer is ok. Thanks

Ok, so I'm doing a reseach project for biology. I'm studying UV rays and using color changing beads to test how they react to different colored lights by seeing what color they change to. I tested the beads under the light and I placed the beads on a bed of aluminum foil, thinking it would speed up the process, How long does it take for the beads to change color, and how can I speed up the process?

This is the original question.

You have two pure breeding strains of gold fish. Strain 1 has but one large dorsal fin, while strain 2 has two such fins. You cross them together and all of the progeny have a single dorsal fin. You then mate brothers and sister together and to your utter amazement only 1 in 16 progeny has two dorsal fins. How do you understand this?

I understand the 1st breeding part.
For example GG X gg (GG for 1 dorsal fin and gg for 2 dorsal fin) -> all progency will have Gg genotype and 1 dorsal fin.

However how can they get 2 dorsal fin 1/16 possibility in 2nd breeding?
