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
Mendelian
