What is lignin and its role in plants?
Why can reducing the amount of lignin in trees enhance the
efficiency of cellulostic-ethanol production?
Why can't trees be genetically engineered without any
lignin at all?
5Gº
Why are transgenic approaches rather than traditional
breeding being used to create trees with altered levels of
lignin?
Where can you find the only company in the USA that
makes transgenic trees that are found in forests?
Go to this company's website. What type of endangered
tree are they trying to survive?

- Imagine you are trying to test whether a population of flowers is undergoing evolution. You suspect there is selection pressure on the color of the flower: bees seem to cluster around the red flowers more often than the blue flowers. In a separate experiment, you discover blue flower color is dominant to red flower color. In a field, you count 600 blue flowers and 200 red flowers. What would you expect the genetic structure of the flowers to be?arrow_forwardVISUALIZE Use two different colors to depict the unduplicated chromosomes of species C with larger chromosomes (2n = 8) and species D with slightly smaller chromosomes (2n = 10), and of their F1 hybrid.
