Lab puppies?

Question

Just curious, if the female is Black and the male is Yellow, what color will the puppies come out?

Answer 1

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.

Answer 2

Before I got my labbie mix his litter was black and yellow! One is more of a whiteishyellow. One was a Tan and 3 were yellow. The rest were black.

The mom was a Yellow lab. I am not sure about the dad though.

So the puppies would be a mix of black and yellow.

Answer 3

Well if you're lucky you will get a fairly even mix. But black is a more dominant color with labs, so I would guess you would get more black then yellow.

Answer 4

My science teacher told me that, dog reproduction is different from human reproduction. Dog's color may not turn out the color you expect, theres way more to it then mixing two genes together. However, most likely it will be brown but there are many other possibilities that are likely

Answer 5

Either color can show up in the puppies,& I think a brown may also be possible..

Answer 6

Probley a mix Or both Or a choclate lab

Answer 7

purple!
na just kiddin
i think some will be yellow and some will be black :D

Answer 8

Probably a mix of both.

Answer 9

both
