1) Normal specimens (no mutated alleles present), are of course, just that - completely normal in every way. They exhibit no characteristics of the Giant mutation, nor can they be heterozygous for Giant.
2) Giant specimens (one mutated allele present) can get somewhat larger than normals, although this varies, and many exhibit the elongated 'lanky' appearance caused by the mutated allele. Strictly speaking, these are in fact heterozygous and typical rules of inheritance apply when breeding them - the only thing different here is that such heterozygous specimens can now be spotted visually, something that cannot be done with simple recessive mutations!
3) Super Giants (two mutated alleles present) show even more of these effects, growing quite large (specimens weighing over 180gms are known)and exhibiting such an elongated and lanky appearance that even the snout is noticeably longer and more pointed. These are in fact homozygous, and typical rules of inheritance apply when breeding them.
