Meiosis

What is the phenotype of your new dragon?

Which traits are inherited from the mother dragon? AND Which traits are inherited from the father dragon?

Were any traits expressed by the offspring that differed from either or both of the parents? If so, what were they?

How does meiosis allow for variation in offspring?

How does fertilization allow for variation in offspring?

Pedigree and Genes

Now that you know how to breed dragons, let's try some selective breeding in the pedigree view. Use the cross tool to breed a new generation of dragons; breed two of the dragons from this new (F1) generation. Repeat this at least 8 times.

What do you notice about the dragons as you continue to breed more generations?

Use the chromosome tool to closely examine the dragons’ genes. If you had trouble answering the sex-linked question above, now you can observe and compare the X and Y chromosomes…

Can you find any genes that are different among the members of your F8 generation?

How many generations do you have to breed until all the dragons are exactly the same?

You are creating an inbred strain of dragons in the final generation(s) of this process. Write a note describing your strain, and explain what is “special” about all individuals in an inbred strain of organisms.

Explanation / Answer

The phenotype of new dragon is blue.
