The latest news from ron trempers newsletter "In the last years many of you that obtained

my gene for Giant leopard geckos have produced

offspring that are Giant in size from breeding one of

my Giants to a gecko(s) that does not carry the gene

for Giant.

Five such people have asked me if there was a chance

that my gene for Giant was CO-DOMINANT.

My answer has been, up to now, that the Giant gene

was a simple recessive trait.

The first "hets" I made were few in number and once I got pure

Giants it was not needed to produce more such hets here.

Since many more "hets" were being produced by other

breeders, than I produced as a simple step to get the original

pure Giants, I decided to "redo" this "het" step and create a far more

larger group of geckos to study at my end.

I wanted to see what others were reporting.

My new findings reflect that in fact my Giant gene is a

true CO-DOMINANT.

This means that the Giant gene has an equal chance of

being expressed when combined with the gene to be a normal

sized gecko.

Hence, only one Giant parent needs to be present to express

this Giantism in the first generation.

I thank everyone that raised this important question.

Science is great stuff........the book chapter on genetics will go into

all the morphs in detail." (qoute from Ron Trempers e-mail newsletter)
