Today is a very exciting day on the island of Gandwar. Two dragons there are about to have a baby. Because it happens only about every 500 years, the birth of a dragon is met with great anticipation. The lucky parents are Molthwan and Lucenne, two of the island's most admired inhabitants.
Like all eager parents, Molthwan and Lucenne are anxious to know what their baby will be like. Molthwan is especially interested in knowing whether the baby will be born with a fancy spiky or forked tail, a much-admired trait. Lucenne is hoping that the baby will have wings and be able to fly, something not many dragons on Gandwar are able to do.
Try breeding some dragons to see if you can figure out any rules that govern which dragons have a fancy tail. Click the "Breed Offspring" buttons as many times as you like.

Based on these examples, what kind of a trait do you think a fancy tail is? Dominant Recessive
Now see if you can figure out any rules that govern which dragons have wings. Click the button as many times as you like to breed possible children from these pairs.

Yes No
Do you have an idea about how wings are inherited? Try the two scenarios below to see if they confirm your suspicions.

Below is a dragon and its chromosomes. You can control and change the dragon's alleles. Try changing some using the pulldown menus and see what happens. Experiment with the alleles for tails and wings to see if you were correct.
What other traits can you change on this dragon? Find one trait you think is particularly interesting, and use the button above to take a snapshot for your lab notebook. Use the toolbar to point to or circle the trait, and write a note in your notebook describing how you caused that trait to be expressed. (Note: You can view your notebook at any time by clicking the notebook icon at the lower right.)
