8-page illustrated article provides a simplified overview of
coat colour expression
and
inheritance in Bull Terriers. Understanding does not require
any existing genetics knowledge and it uses simple descriptive
language in order to use the Bull Terrier Colour Probabilities
Calculator Tool which follows.

Bull Terrier Breeder's
Tool: Colour Probabilities Calculator
This 1-page form can be used to
calculate the colour probabilities for any chosen litter
of Bull Terriers. It uses input
information of the colour of parents and grandparents of
the
mates and their observable extent
of white, base coat colour and brindling
pattern.
