#Unit 1. Molecules and their Interaction Relevant to Biology

Lipids as pigments in plants and bird feathers.

Birds acquire the pigments that color their feathers red or yellow by eating plant materials that contain carotenoid pigments, such as canthaxanthin and zeaxanthin.

The differences in pigmentation between male and female birds are the result of differences in intestinal uptake and processing of carotenoids.

Once wingless and engrailed expression patterns are established in adjacent cells, this pattern must be maintained to retain the parasegmental periodicity of the body plan.
