Midget lab is yellow, mum was yellow an I *think* dad was black, but would have to check.

Her body is quite light yellow, but ears are a good bit darker, almost the fox red colour. Three of the other pups in the litter were chocolate and the other one was yellow. A light one. The mum was one of those almost white yellow labs.

If you were to put Midget to a chocolate lab, I would assume a mix of yellow and chocolate pups?? Hopefully a fox red or two...but no black ones?

Anyone any ideas?
 
does she have normal pigmentation or pigmentation like a choc lab?
ets...not that neccessarily Im any more likely to be able to give you an answer, I'm **** at genetics! :p :D
 
Im not sure how colour genetics work :o but Yellow Dogs mum is a black lab and his dad yellow - the whole litter was a mix of black and yellow. The second time his mum was bred from the breeder used Yellow Dogs dads full brother who was also yellow and the litter had 2 chocolates in it.

Within Humans, you have recessive and dominant genes which can lay dormant for generations. I would say that if certain colour genes were present in her DNA make up than she could theoretically have blacks because the Brown could also be a carrier of the black gene.
Again within humans (which I am basing this on) you could have a great, great grandfather or mother who were black and white family after that (due to marriage blah blah). Depending on the white mother and father, there have been instances of them having a black child as both the mother and father carried that recessive gene which when they made the baby, there was no dominant white gene so the baby is black.
The same happens with ginger people blonde people blah blah.

Hope this helps
 
My dog is Fox Red - he was the only yellow(ish) in a litter of blacks from 2 black parents. His only litter so far, with a lighter reddish lab came up with all the pups between the shades of their parents - all the reddish shade of yellow. So we're guessing from sample size n=1 that fox red is recessive... But it is a guess.

2 Chocolates apparently always makes chocolate - so that's recessive - not sure where red comes in relation to that though!
 
Putting a yellow to a choc is`nt a good idea..that is how you get those pink rings around the eyes ,caused by lack of pigment.To get good dark pigmented chocs it is choc to choc..but feed in a black regulerly for depth of pigment.Red ia a different gene to yellow ,so even a yellow needs the gene in there somewhere to produce true reds..as opposed to dark yellows.
The best reds are in the US,certain kennels have managed to breed dark red show type labs that can also work well.They are an amazing colour ..almost an Irish Setter red in some cases.
 
I would read up a bit more into colour genetics in your breed.

FI for us, sable is a dominant gene, you need at least one sable parent to produce sable puppies.

The litter my two were from was a sable to a rich black and gold and there was one sable male, two sable females, one very well pigmented black and gold male and one very well pigmented black and gold females.
