Giant Leopard Gecko Morph Description
The giant-sized leopard geckos are divided into two classes called Giant and Super Giant.
In the Giant class, the males reach 80-110 grams, and the females 60-90 grams per year of age. This being their typical size for the Eterozygotes.
It should be noted that these giants can appear in any phase, pattern, or color. Unless both Super Giant parents are used, there is no visible way to distinguish a Giant from a Super Giant until 10-12 months of age.
Giant Leopard Gecko Morph Origins.
The Giant morph was developed by Ron Tremper in 1999.
The event was a surprise and it was not until a little less than the first year of age that the male juvenile, a product of crossing two normal leopard geckos showed signs of mutation. This specimen reached a length of 11 inches at 10 months, after which it did not grow anymore.
Ron Tremper decided to check if the giant’s trait was a new mutation. For this, he employed albino females in the hope of obtaining heterozygous offspring that gave giant trait signals. His tests were successful on the first attempt, giving rise to the first albino giant. Later it demonstrated the presence of a co-dominant or at least incomplete dominant gene for giant morphs.
The second part of the test was to match the giant albino with sisters of the normal type. The product of this union was given to a group of females that by their size did not indicate that they were giants, which were crossed with the original giant, resulting in the first generation of super-giant.
