The venom ranges in toxicity level from mild to extremely toxic. A gland called the Duvernoy's Gland produces the venom of these snakes. (Kept this as it shows other yypes other than boide)

The two alleles may be different mutants or a wild type allele paired with a recessive mutant or a dominant mutant or a codominant mutant.

Inclusion Body Disease is thought to be caused by a retrovirus. Also known as IBD.

Infralabial: the scales on the lower lip.

Intergrade: 1. An animal that comes from an area where the ranges of two subspecies meet and that shows some characteristics of both subspecies. 2.

Sexual Notation

males.females.unsexed

This is always used to note the sexes of reptiles of the same species and sub-species.

So, if you have 1 male and 2 female royalls, you would write:

1.2.0 royal pythons

Or, you may drop the unsexed column if it is not needed

1.2 royal pythons

If you have 1 male and 1 female and 6 of undetermined sex, you would write: 1.1.6

If you only have 6 of undetermined sex, you would write: 0.0.6
