Yellow and chocolate labs mating?

Question

what would be the result of the puppies colors?

Answer 1

It depends on whether the chocolate lab is carrying yellow recessively or not.   It also depends on whether the yellow has a black nose and is carrying the chocolate recessively, or if the yellow has a black nose and is pure for black.

B - black

b - chocolate

E - full pigment

e - pigment reduced to yellow

Bb and BB are black

bb is chocolate

EE and Ee are full intensity (black or chocolate)

ee is yellow (black nose if B present, brown nose if bb)  

bbEe (chocolate lab) x BBee (yellow lab with black nose)-->

25% BbEe (black)

25% Bbee (yellow with black nose)

If the chocolate parent does not carry yellow

bbEE (chocolate lab) x BBee (yellow lab with black nose)-->

100% BbEe (black)

If the yellow parent is Bb (chocolate carrier) instead of BB (pure for black) you would get pups in all colors.  Some of the yellows would be BB (black nose) and some would be bb (brown nose).  THe breed standard calls for yellows to have black noses; brown nosed yellows are penalized.  Why?  Who knows.  Seems pretty arbitrary.

sorted you cannot know how many of each you will get.Tilks Mom

Answer 3

This pairing results in some blonde pups and some brown.

Here are the genetics of the cross.

Answer 4

Poor.  That's what they'd be.

I happened across an article that discussed this exact match.  You get dull looking yellows and diluted chocolates.  None of them will have ideal coloring.

Answer 5

You could have Chocolate, yellow, and possibly black and any mix of the 3.  

You could also have a solid litter, but according to this chart, all yellow would not be possible. But, genetics are known to go angainst charts and predictions.  

Depends on the genetic make-up of the dogs being bred.

Chocolate + yellow = one of the following

All Black

1/2 black + 1/2 chocolate

All Chocolate

1/2 black + 1/2 yellow

1/4 black + 1/2 yellow + 1/4 chocolate

1/2 yellow + 1/2 chocolate

Answer 6

Color genetics aren't quite as  straight forward as what you see on the surface of the dog (phenotype)

It would depend on whether your yellow lab also carried the recessive brown gene (E Locus Yellow and Chocolate/Brown factored) or had a red nose (Elocus and homozygous for the chocolate gene) and whether or not your chocolate lab carried a recessive gene for E-locus yellow.

You could get an all Yellow litter, carrying the Chocolate gene or a mix of Yellows and Chocolates, all three colors or just blacks.  Here is a color chart to help you understand better:
