I actually went hunting for the answer to this on the internet, and according to this site http://www.blueknightlabs.com/color/coatcolor.html it appears that no crossing of chocolate labs can have puppies that are black. Chocolate labs can only have yellow and chocolate offspring. At least that's how I read it anyway. A black lab x chocolate lab can have puppies that are black, yellow, or chocolate, depending on their pedigree. A chocolate and yellow lab can have puppies that are black, chocolate, and yellow. Chocolate x yellow lab crossing can also have puppies of all 3 colors. But yellow lab x yellow lab always have yellow offspring. What gets confusing, is that it appears some yellow labs are chocolate colored, but contain no black pigment NBP in their genes. These are the eebb yellows, pure recessives. This would be pretty darned rare, just from looking at this chart. But even if you bred one of these NBP chocolates colored yellows to any other normal chocolate, they still wouldn't have black puppies, they'd all be brown or yellow. I'm wondering how that breeding you describe is having black, yellow, and yellow puppies Rednosered if this chart is correct. There is no way, according to this chart, that 2 purebred chocolate labs could have black puppies. I would suspect that one of those chocolate labs is actually a fox colored yellow, since yellows vary in color from the almost white yellow shade to fox-red in color. Chocolates can be a light color or a dark color. I imagine a light colored chocolate could look very similar to a dark colored yellow.
I've never seen the puppies myself, just spoke to my husbands friend about the pups. That's probably it,he has the chocolates he breeds. It's only like once a year he has a litter.My husband has met the parents,he says they are beautiful dogs. It's his friend that got me curious about the Labs.
I reckon the only way to know for sure would be for your friend to breed both dogs a few times with other dogs they knew for sure were yellow, like the light cream ones. If all the puppies in one litter were yellow, and some of the ones in the other were brown/black/yellow, you'd know which was really the yellow. now you've got me curious though! We need pictures, to compare which is the true yellow lab please ;)
brown lab or any choc dog It has been my understaniding that the black gene is not present in the choc color. The nose is usually liver in color, the eyes blue/green, feet pads are pink in color with sometimes dark brown spots. The toe nails are clear with pink quick. This info was passed on to me when I was looking for my chocolate Cocker Spaniel. Now her mother is black and the dad was choc and white parti. Out of the litter there were four choc and white partis, 1 chocolate, and 1 black. In this litter, the only one having any black gene would be the black one. All the rest are considered chocolate, even with the chocolate and white.
my cocker is black, her mom is chocolate and her dad is buff. they had 4 buff pups and 3 blacks. i think it all goes back to the lineage of the parents and grandparents. jason that site is pretty cool...
Genetics, A male will have 2 gene types a domiant and a recessive, say B for dominate and b for recessive and a female will have 2 also B & b So that will give you a phenotype (what the pup will look like) of: 2 BB 1 Bb 1 bb So that means that the B are dominate and will be Chocolate and there is 1 bb that will be recessive and will be black.. I had a black lad as a child and her parents were both yellow. It is a genetic trait that is the luck of the gene pool. It is the same with parents and children. Two blond parents can have a redheaed child.
