would you get blue staf pups if we breed our black staff with a blue stud?

Answer 1

well, that depends on the genes of the parents. you might end up w/some that are black and some blue..but then, since staffies come in a variety of colors * and chances are that your staffies have other colors in the family tree* don't be surprised if you get a white, or tri or even a brindle. *blue and black brindle..wouldn't that be pretty!*

i had a black lab, that was bred to another black lab. she had 4 black pups and 3 yellow pups...because somewhere in one of the parents family tree was a yellow lab.

funny thing mother nature.

Answer 2

It really depends on whether or not your black girl is carrying blue.

If she had a blue parent then there is a possibility that 50% of any puppies will be blue.

Colour genetics - the technical bit:
A dog's appearance (“phenotype”) is determined by the genes that govern the expression of that trait (the “genotype”). For every trait, from eye color to coat length, a dog has two genes, one inherited from each parent. In some instances, a dog receives the same form of a gene from both parents in which case the dog is said to be “homozygous”. If the dog receives different forms of a gene, the dog is “heterozygous”.

When a dog is homozygous, there is no question as to the dog’s phenotype. Since the dog only has one form of the gene, it expresses the form called for by that gene. Thus, a dog that is homozygous for blue coat colour has a blue coat.

However, when a dog is heterozygous, the different genes, generally, do not create a “blended” effect. Instead, some genes are always expressed in the dog’s appearance while other genes are hidden unless the dog has two copies of that gene (i.e., the dog is homozygous). Genes that are always expressed are said to be “dominant” while genes that can be hidden are “recessive”. A dog that is heterozygous for a trait has one dominant and one recessive form of the gene for that trait. Since a dominant form is always expressed, the dog’s phenotype shows the type called for by the dominant form and the recessive form is hidden. For example, a black dog that is heterozygous for blue carries a gene for blue. However, because the black form of the gene is dominant to the blue form, the dog is black.

If we call the dominant gene for a black coat B & the recessive gene for a blue coat b - then the blue stud can be said to be bb.

If your girl has one blue parent then it is likely that she has one b gene & one B gene - so she is Black because the blue is hidden.

A puppy inherits on gene from it's mother & the other from his father. In your case, all the puppies will receive b genes from their father but they can receive either B or b genes from their mother. The possible combinations are: bb (blue) or Bb (black) - so on average half of the puppies in the litter will be blue.

However, if your girl had black parents then it is possible that her phenotype is all BB - in which case all of the puppies will be black (bb x BB = bB). Though her one parents might have had the recessive gene for blue & passed it along to your girl unexpressed ... have a look back in her pedigree for blue dogs.

Sorry that was so long winded - hope that you got the gist. Please note I haven't mentioned any other colours than blue & black as felt it was complicated enough!

So the answer is - if your girl had one blue parent then on average 50% of the puppies will be blue. If your girl's parents were black but she has blue in her pedigree then there is a small chance of blue puppies but you won't know for sure until they are born.

Please also note - the chance is on average 50% - this doesn't guarantee that exactly half of the puppies will be blue.

Hope this helps.

Oops, sorry think I went a bit OTT on the answer!!

Answer 3

the black gene is dominant so you would get black ones carrying the dilute (i.e. blue) gene. If you then mated these together, you would get some blue and some black. So if your black staff has a blue gene somwehre, you may get some blue pups. You need to be able to read your one's pedigree and know what colours all the dogs colours were. Genes are not just about the first 2 generations. That goes for temperament aswell as colour.
Ideally you wouldn't breed your staff at all because of the tens of thousands of unwanted ones including litters of puppies, which end up in rescue kennels all over the UK.

Answer 4

Depends on which colour gene is dominent, an whether the above dog has a blue gene also, this is a genetics question.

Answer 5

I got a blue staff whose parents where both brindle, I think it depends on the whole ancestry, if the black staff has blue ancestors then maybe.

Answer 6

im not sure on the answer but i do know that here in aus there a plenty of people even a registerd breeder that has a black ***** and blue dog but is selling pups as blue.

Answer 7

black it a dominate color so i doubt you would get a true blue. possibly half and half.much like a beagle which is brown and white so you would get 50-50 blue and black but you may get one pure blue.depends on size of litter and the parents parents colors.

Answer 8

it depends on whether your girl has the recessive gene blue...you could get a mixture of both but some will carry the blue recessive gene...
