Colour line Common Green Iguana
The blue and red animals of the trade. These are selected lines rather than single genes, so no offspring percentage applies, and much of what looks blue or red in a photograph is a juvenile or a male in breeding condition.
How it is produced
- Where it comes from
- This is not a single gene. It is produced by choosing which animals to breed, over generations.
- What that means for breeding
- No offspring percentage can be given for it. Breeders judge it by looking at the parents.
Offspring odds
No numbers for this one.
Colour line is produced by selective breeding over generations, not by a single gene, so no offspring percentage can be given for it. Breeders judge it by looking at the parents.
Worth knowing. Hatchling green iguanas are bright emerald and adults are not: they dull to olive, grey or orange-brown, and mature males go orange in season. The animal in a photograph is usually a 20 cm baby that grows into a metre and a half of lizard needing a room-sized enclosure — which is why this is among the most commonly abandoned reptiles in the trade.
What this rests on
Established by breeders through repeated crosses and recorded in community documentation, not by published genetics. That is how almost all morph inheritance is known — and it is worth saying rather than presenting it as laboratory fact.
