What are some of the ways to make leucistic ball pythons

[pythontricker]

Fire x Fire = Black Eyed Lucy
Lesser x Lesser = Blue Eyed Lucy
Mojave x Mojave = Blue Eyed Lucy
Butter x Butter = Blue Eyed Lucy
Lesser x Butter = Blue Eyed Lucy
Lesser x Mojave = Blue Eyed Lucy
Mojave x Butter = Blue Eyed Lucy
Pied x Lesser = All white Pied (Unsure of eye color Lucy)

Lessers = $700 - $1500
Butters = $1200 - $1800
Fires = $1000 - $2000
Mojaves = $300 - $700
Pied = $1000 - $2500

Prices are ranges I have seen for 08 babies and depend on breeder and details that people look for when buying.

For the Mojave to Mojave What percent of babies are Leucy?
