Giant question

[Mallie]

I recently picked up a really gorgeous Giant Tremper Patternless from a reptile show and I can't wait to breed it. I don't have any other giants though so it would be bred to a normal. I failed to ask if the giant came from two giant parents or just one.
So my question is what would you sell Giant x Normal babies as?

Possible Giants.

Awesome. Thanks!

Yeah half should be giants and half should be normal if I'm not mistaken.

Gigantism (that's fun to say... isn't it) is a line-bred trait by most accounts. That mean's there's no single chromosome that controls it.... So like Tony says the offspring are "possible" giants... Just like if your dad is a fat bastard, there's a good chance you will be to, but your not doomed by a single chromosome.

Geckos line bred for larger size are not the same as Giants. Giant is a codominant trait discovered by Ron Tremper. The reason hatchlings are sold as "Possible Giants" is that they can not be positively identified until later in life, though there are certain characteristics that can strongly hint that a young gecko is a Giant like a long, lanky body and elongated head.

Yeah I have saw one big Leo in person he was around 100 grams but he wasn't a giant, like Tony c said the longer head and body make it a giant. With more surface area they have the ability be heavier then normal leos.

hmm, I hear what you're saying. I would say that co-dominate traits are hard to distinguish from multiple allele traits, ie line bred traits. Especially for something as hard to quantify as the "giant" phenotype. Without actual DNA tests, you're relying on multiple generations, and some subjective phenotype definition that is "giant" to make the co-dominance case.
