I want to know In what numbers, some characteristics flow down in generations? How mant specimens are required to qualify for a BREED? How to achieve a breeding plan for certain characteristics?
Suppose I want to have breed of Blue Goldfish, what step should be followed up?
Do you know any good link on the subject?

Hmm, your first question is vague.
A breed is not defined by its numbers.
A breeding plan? The first rule is to use as many starting individuals as is economically practical, to avoid inbreeding.

Goldfish were developed over centuries of selective cross breeding. A "sport" is what a unique specimen is called. If you breed an animal and one of it's offspring is different from all the rest you have a "sport" and starting point for a different color morph or variety. Wild goldfish are called carp. If you are looking for a specific color, size or shape in a species you select the individual which best fits the characteristic you are looking for and generally breed it back to it's parent or maybe a sibling if available. Then you repeat with the next generation until you achieve what you set out to do. Sports or Morphs are fairly common in captive bred goldfish but more rare in wild fish due to inbreeding and the lack of genetic diversity.
