The world's first breeding of a patternless female BCI by a patternless male BCI produced a lovely litter of healthy Sterlings today.
I think it is safe to conclude that the Sterling gene is a simple recessive mutation.
I have twice bred het x het (4 different Boas) producing roughly 25% visual Sterlings in each litter.
I have twice bred Sterling x het (3 different animals) and produced roughly 50% Sterlings in each litter.
I have bred a Sterling to an unrelated super-hypo and produced no Sterlings (all hypo het Sterlings).
And today, Sterling x Sterling has produced a full litter of Sterlings.
I'm kind of over the moon. What a great day.
Here's a few pics.
Thanks for looking.
