Ahhh, the Rusty talks again....
Rusty is a hypo type black rat. There are two strains of them, broken in northern or Ohio and the southern which I think came out of KY... I forgot. The more popular and abundant being the southern strain. I never heard of the Northern strain until I lived in Ohio and went to a show up there.
They do produce the leucy trait, though not every clutch. I have had some who produced for two years with no leucistics only to have them produce a half and half clutch the next year.
Here is the cool part, when you breed both strains together you get all normal babies het for both strains right? Well you do but if you breed those babies back to each other you get a 50/50 mix of normal and rusty. The issue there? is one strain co-dom and the other dom??? And I know what some people think about the hypo claim but it was proven by Dr. Bern and then by Dwight Good. Now, what is a brendle? Rock On, BLue
