Click here to practice your selective breeding skills.
1. How can you create the largest crop?
2. Can you think of problems and risks associated to inbreeding?

NOTE: Nearly all domestic animals, including horses, cats, and farm animals (and most crop plants) have been produced by selective breeding. Selective breeding allows only those animals with the desired traits to produce the next generation.

RECOMBINANT DNA

1. CLICK HERE for an animation that shows how recombinant DNA (rDNA) is formed.
1.1 Why do we need a plasmid?
1.2 Can you think of ways recombinant DNA is used by geneticists?

2. CLICK HERE for a tutorial on Recombinant DNA.

3. This tutorial from the University of Delaware is a great step by step guide into how to create Recombinant DNA.
