Breeding

Question
Hello there
I'm really hoping you can help me, I breed a chocolate otter to a blue fox, I got 2 black otter, 2 blue, one vienna marked, a black vienna marked, and a blue dutch split.  Some of the colours weren't what I was expecting, like vienna marked and dutch split, please could you explain how come they were in the litter?? Thank you for your time

Answer
hi Michelle the reason they were in will have depended on there family tree .
sometime in the past some one must have been experimenting with the parents or grandparents to see what they could produce and now further on the line yours have thrown up these strange colours.
Dave.
