Dragon Genetics Questions: Competency 8 Performance Assessment
Part 1: Intro and Rules Questions

What rule governs inheritance of the fancy tail?
What allele combinations yield a fancy tail?
How are wings inherited?
What allele combinations yield wings?
What rule governs inheritance of horns?
How are legs inherited?
What rule governs fire breathing?
Explain your answer to the fire-breathing question.
What type of trait is color? 
Explain how color is determined in dragons. 

Part 2: Meiosis Questions

Can the father dragon provide the required alleles to have a winged, legless dragon child?
Can the mother dragon provide the required alleles to have a winged, legless dragon child?
Complete the crossing over exercise and take a screenshot of your results (not a virtual lab notebook snapshot). Paste your screenshot into a Word document (make it very large so I can see it) and explain how your efforts would result in a winged, legless dragon child. Save your document and upload it here.
Breed your dragons and take a screenshot of the results. Paste your screenshot into a Word document (make it very large so I can see it). Save your document and upload it here.

Part 3: Pedigree and Genes

Examine dragons of your F8 generation. Are there any alleles that are different? Take a screenshot (not a virtual lab notebook snapshot) of this generation. Paste your screenshot into a Word document (make it large enough for me to see) and explain what alleles are different. Save your document and upload it here.
How many generations does it take until all the dragons are the same? Take a screenshot (not a virtual lab notebook snapshot) of this generation. Paste your screenshot into a Word document (make it large enough for me to see). Briefly discuss your mating scheme to get to this generation. Save your document and upload it here. NOTE: If you reach F30 and still have differences, take a screenshot of that generation and discuss your mating scheme.
What is something noteworthy about inbred strains of organisms?

Part 4: The Plates Problem

Is it possible to determine how the plates on a dragon’s neck are inherited by examining the offspring of the first pair of dragons? Explain your answer.
During the course of your pedigree crosses, what could you determine about the inheritance of neck plates? Explain your answer.
Where do you think the gene for neck plates is located? Why do you think this?
Based on what you know, what trait seems to indicate a dragon will grow plates later in life? Why do these two traits stay connected?
