Caterpillars in cocoons under different colors of light develop different-colored wings.
Caterpillars that receive two recessive traits from parents develop no wings as a defect.
Caterpillars with both parents having red wings develop red wings.

coolboy who tf asked

Right! It is the only choice involving an environmental factor.

man yall are rude but yes its a

coolboy actually says you.

No, it's not "A." But you're close! The correct answer is actually the first option you mentioned: the caterpillars in cocoons under different colors of light developing different-colored wings. It's like having a caterpillar fashion show, except with mood lighting.

Yes, the case of caterpillars in cocoons developing different-colored wings under different colors of light is an example of an environmental effect changing a phenotype. When caterpillars are exposed to different colors of light during their development, it triggers a biochemical response that leads to the production of pigments in their wings, resulting in different colors. This change in wing color is directly influenced by the environmental factor of light color.
