Tremper Albino Leopard Gecko



REPTILES Magazine Bonus Content

In the 1960s I remember fantasizing with my fellow herp buddies about when the first albino reptiles might appear. We wondered if albino California kingsnakesball pythons or even leopard geckos would be a reality in our lifetimes.

In September 1996 I received a phone call that changed the leopard gecko industry forever. Two clients of mine reported that they had hatched an albino leopard gecko (Eublepharis macularius) from a wild-imported female. I requested a photo. Sure enough, it was an albino leopard gecko. I was amazed and excited.

It turned out that the albino leopard gecko was female, Rosie, and her sibling was a normal-looking male leopard gecko. I kept in touch with the owners of this rare gem for a year and helped them with breeding ideas, genetics and a marketing plan.

Rosie, the albino leopard gecko, was born by Bubba, pictured here

Bubba the leopard gecko fathered Ron Tremper’s line of albinos. Tremper achieved success with this breeding project in April 1999.

An Uncertain Start

In October 1997 I learned that they did not have any luck breeding Rosie with her brother. They wanted to sell me the pair of leopard geckos. A meeting was immediately arranged, and a purchase-royalty contract based on any successful commercial propagation and sales of the first albino leopard geckos was signed.

I’ll never forget seeing Rosie for the first time. She was smaller than I expected and not showing any ova through her belly wall at 1 year of age. Her owners said she had been sick during the year, so before signing the purchase contract, I mentioned that it was unlikely Rosie would be the founder of the first albino leopard geckos. I was betting on her brother for success. After all, based on Mendelian genetics, he had a 67-percent chance of carrying the albino gene.

Upon returning home, I set up the pair in quarantine and decided to keep the project totally secret. Rosie showed signs of appetite loss after three weeks, and her health failed rapidly. Despite my best efforts, Rosie died, leaving the entire albino project on the shoulders of her brother, who I named Bubba.

Bubba Gets His Chance

An 18-month-test-breeding plan was conceived to determine whether Bubba carried the albino gene. In the spring of 1998 he was bred to 20 of my best designer leopard gecko morphs: tangerines, stripes, reverse stripes and jungles. Because incubation temperature can control the sex of leopard geckos, I controlled the resulting offspring to be approximately 10 males and 150 females.

Late in 1998, I began the laborious task of breeding Bubba back to his 150 daughters. Daily grading of follicle development in each female was necessary, so females could be bred to their father in the proper order, thus reducing the chance of infertile eggs. Cage by cage Bubba was moved each day to a new trio of his offspring, and soon some 1,200 eggs were incubating.

The scene was set. It was all or nothing. If Bubba indeed carried the albino gene, then one out of eight incubating eggs could be an albino. If he was merely a normal leopard gecko, then all the work would have been for nothing, and the leopard gecko albino gene would have been lost.

The Project Succeeds

In mid-April 1999 my eyes fixed on the albino-project egg boxes in the large incubator. The very first egg of the test-breeding project had hatched. To my amazement there lay an albino leopard gecko hatchling. I was in complete shock and celebrated our secret triumph.

Mathematically, a breeder could expect 150 albinos from the 1,200 eggs, and during the next few weeks some 155 albinos emerged. The world’s first captive-bred albino, soon named the “Tremper albino” by the herp community, debuted during the summer of 1999. I let out 100 adults that year, and to this day the Tremper albino leopard gecko line is the most commonly occurring strain with some tens of thousands of descendants worldwide from Bubba, the grand patriarch.

Bubba is still alive and producing young again this year. It is hard to imagine that his hidden genes have given rise to the Tremper albino, super giant, carrot-head, aptor and raptor mutations, and much more in the field of morph development. He is truly the Cinderella story of leopard gecko breeding.
