4. Smaug's parents are not described by Tolkien, but we can use our current model of genetics to predict their phenotypes. To make this question easier, assume that all possible male offspring look identical to Smaug. In the space below, predict the genotype and phenotype of both parents. Please note, there are multiple possible answers to this question, you only need to predict 1 possible scenario. If a specific locus could contain either allele and still produce "Smaug- like" offspring, represent that locus with a dash (-). Show your work.

Question
![Smaug (The Chiefest and
Greatest of Calamities, The
Unassessably Wealthy, The
Stupendous, etc.), is the dragon
who lords over the Lonely
Mountain in J.R.R. Tolkien's The
Hobbit. He is described with the
following phenotypes:
Reddish-golden scales
Batlike wings
Fire breathing
Let's assume the following inheritance models are true for the dragon phenotypes
observed:
Phenotype
Scale Color
Wing Shape
Fire Breathing
Alleles
R¹ (Red scales), R² (Gold scales)
X¹ (Bat-like, Dominant),
Xi (Insect-like, Recessive)
F (Fire breathing), f (unable to create
fire)
Inheritance Model
Incomplete dominance
X-linked allele
