If a black labrador and a yellow labrador mate, what colors will the puppies be?

Question

Will they mix or still have a litter of one type color?

So they would never be half back and half white or have spots?

So they would never be half back and half white or have spots? Why is that?

Answer 1

They can be any colour that Labs come in. Even though neither of the parents is chocolate, this doesn't mean the chocolate gene isn't carried in the pedigrees.
No, they would never be a mix of two colours, nor would they have spots.

Answer 2

Yes it could very well show up in any litter. Brown, Black, and Yellow are all the colors of Labrador Retriever's so depending on the most dominant and recessive genes in the line, and the lineage from other sires and dams, etc. there is a chance some of the puppies could come out brown or black. However, if both dogs were Yellow, then the majority of the litter is likely to be yellow, because you have 2 of the same colored dogs breeding.

Answer 3

A Black Labrador

Answer 5

My Lab's parents were one chocolate and one black and all six puppies came out all black and one (my dog) came out black and tan, which is from a recessive gene which needs to be in both parents.

Also, there are really only two coat colours, Black and Brown. The Yellow dog is not the result of a colour gene, but rather the inability to Express a dark coat colour.

Answer 6

This question was asked yesterday so I'm going to use my same answer.

It depends on the genes of the black dog. If the black dog is a carrier of the yellow gene you can have yellow and black. If the black doesn't carry the yellow gene you'll have all black.

BB-this means the dog is black, and does not carry the yellow gene.

Bb-dog is black and carries the yellow gene.

bb- dog is yellow.

In order to be yellow a dog has to have both of the recessive genes. Black is a dominant gene. A dog with both a recessive and a dominant color gene will show the dominant color but can produce pups with the recessive color if bred to another dog that also has the recessive gene.

So if your male dog is BB and is bred to a bb the pups would all be black, but would carry the recessive gene.

If your male is Bb and is bred to a bb, say they have four puppies you could end up with two black pups who carry the recessive gene, and you could end up with two yellow pups.

A yellow dog bred to a yellow dog will produce only yellows.

But remember its also pure luck which genes the pups will get. So even with the probability in the example with the four pups, you could end up with all blacks carrying the yellow gene, or you could end up with all yellows.

If the black dog bred to a yellow dog produces a yellow pup, you know which genotype the dog is, he is a Bb.

A couple more examples, say you have two black dogs, they are both Bb. In a litter of four pups you could end up with black pup who does not carry the recessive b (a BB), two black pups who do carry the recessive b a (Bb) and one yellow (bb) pup.

If you have two black dogs, one who carries the recessive (Bb) and one who doesn't (BB), all the pups will be black, but you'll have some who carry the recessive (b) and some who have both the dominant gene (B). A litter of four pups would look something like: BB, BB, Bb, Bb.



Great link Loki, simple genetics, just not as simplified as I made it. Love it, added to the favs, thank you.

Answer 7

I'm not a geneticist so I can't fully explain why, but two dogs of a breed that only has solid colors will not create spots because its just not in their genetic code to do so. The same reason that you don't see a blond mom and brunette dad with kids with blond hair with brown spots.

Answer 8

If the black labrador is dominant for color in alleles, it should have a BB or Bb, and the yellow will have a bb. The recessive allele is the yell coat. It could end up all the puppies will be Bb, and they will all be black, or that the puppies will be half and half.

Answer 9

Usually it's a mix. I know of one where the father was yellow and the mother was black. There were 6 pups in the litter, three yellow females and three black males. The pups were from the breeding program for Leader Dogs for the Blind, and I got to raise one of the females for a year. She went on to graduate and become a Leader Dog.

Answer 10

Depends on the colors behind them.

Black is the dominant color in the breed. So probably lots of those.

No. You will never get a part-colored or spotted Labrador...at least not a purebred.

Not very common, though. :)
