In a species of flying dragons, the gene for fire-breathing is linked with the gene for temperament. Each gene has two loci and have a completely dominant inheritance pattern.
The allele for fire-breathing (F) is completely dominant to the recessive allele for non-fire-breathing (f). The allele for angry temperament (A) is completely dominant to the docile allele (a).
A male dragon heterozygous for both loci mates with a non-fire-breathing, docile female producing the following offspring:
63 fire-breathing, angry
11 fire-breathing, docile
16 non-fire-breathing, angry
59 non-fire-breathing, docile
