ok if i have a black dog crossed with a brown dog which would be the dominant and which would be the recessive? would you know that? i do know that if the brown was recessive then the only way for it to turn out brown is if the dog is homozygous recessice. can anyone answer this question or do you have to have more info??

Depends which is dominant. Lets assume the black is dominant. If 2 black dogs mated they could have a brown puppy but they would have to both be heterozygous so the parents would have a B black allele and a b brown allele. The black would take over for both parents and the parents would both be black but if the puppy inherited both b alleles from both parents he would be brown. there would be a 1/4 chance of him being brown. If a brown and black dog mated it could be brown but only if the black dog was 'Bb'. However if just one of the parents was homozygous black the puppy would DEFINITELY be black.
Parent 1: Bb Parent 2: Bb
Puppy possibilities:
BB - black
Bb - black
Bb - black
bb - brown
Parent1: BB Parent 2: Bb
Puppy possibilities:
BB - black
Bb - black
BB - black
Bb - black

Black is dominant, brown recessive.

Black is the dominant color. But you have to take into play the colors of the parents of each dog. Because they have handed down their "color" genes to these dogs. And they might get messed up in there somehow. I guess the only sure way to tell is if they're Purebreed.

hair color is not a dominant or recessive thing. it could be black or brown or black with brown spots or could come out white or gray or any other dog color... it all depends on its own genetic make up and it's grand parents and great grandparents etc.

i think black is more dominant than the brown

Well, it depends on what color the offspring is. But probably recesive brown and dominant black.

hmm.. based on what i have learned in genetics, i think that the color of the offsprings would be unpredictable. its going to be either black or brown. not all will be black or brown. maybe mixed.

You need more information. Do you have the results of the cross? Or does the problem tell you if one of them is heterozygous?
