Two brown dogs mated together will never throw black puppies because brown dogs do not have the black gene. But two chocolate dogs can produce yellow puppies, if each of the parents carries the little e gene – see the bottom right hand box below. 14 авг. 2018 г.
Can two light colored dogs have black puppies?
There is a specific gene that can make a puppy black, no matter what his parents' colors are, and it happens to be a dominant gene. So if both parents are light-colored but they both carry the dominant "black" gene, chances are good that one or more of the puppies will be black or display black markings.
Which dog determines color of puppies?
When dogs breed, the mother and father each randomly contribute one allele from each locus, giving each allele a 50% chance of being passed on to the pups. One of the alleles at each locus is dominant and determines the traits, like coat color, portrayed in the dog.
Can dogs give birth to puppies with different colors?
Black or Liver So depending on the genetic makeup, if black mum and black dad both have a recessive 'b' gene (i.e. they are Bb), the puppies actually have a possibility of being liver (or another colour other than black) as they could get the 'b' gene from mum and dad, making then 'bb'.
Can two golden retrievers have black puppies?
Since all goldens have the recessive “e/e” genotype, it's impossible for a purebred golden to pass on the dominant “E” allele, so they will always be some shade of gold or red, and will never be black.
