A question about genetics

[bouchot]

Hello! I have a black and white labradoodle which you can see in the picture below. Her parents (also pictured below) are a completely different color. This got me wondering...is black and white fur a recessive trait (somehow, I would have imagined he opposite)? Or how is it possible that she got this coat color (not that I'm complaining, I adore my puppy! But I'm curious as to how this works)?

As you can already tell, I know absolutely nothing about genetics. :)

Thanks!

I don't know anything about genetics either, but I wanted to say that your puppy is BEAUTIFUL.

It is complicated for the parti doodles. But Black is dominant to white in non parti doodles.

My doodle is brown, her parents were cream and black. I don't really understand this either but here is a little quiz that shows how the odds work for human eye color. I assume it would be sort of similar.

How fun.  It actually showed why I have three blue-eyed children rather than any brown-eyed ones, even though I have brown eyes.

How funny!  Zoe's parents were both parti's.  Mom looked like your puppy but with different spots, dad looked like the mom in your pics, and Zoe looks like the dad in your pics but she's all black not brown.  She does have pepper fur tho... where there are random silver/white hairs all over and then her butt has more silver than the rest of her body.

OMG! These doodles are all so cute!

I also have no idea but agree that she is just toooo cute!
My boy is chocolate. his mom is white and dad is apricot. I have no idea how chocolate came about.

I'm no expert but I do find coat color genetics interesting.  Looking at the pictures, the mom is a chocolate with white markings based on her chocolate nose.  The dad looks like he is technically considered a "cream" - that sounds crazy but the term actually encompasses all shades from white to dark red.  It appears as though he has a black nose, so I would guess he is a light medium red.

 

Here is a link to an easy to understand coat color chart for poodles,

http://vetgen.com/chromagene-coat-color-b.html, and a coat color chart for labs,  http://vetgen.com/chromagene-coat-color-a.html.  The dad's genotype is probably BBee or Bbee (yellow carrying for black, or yellow carrying for chocolate and black) and the mom's genotype is bbEe (chocolate carrying for yellow).  When you breed those combinations, you come up with some black pups in each litter.

 

I know nothing about parti genotypes, but if you just look at coat and nose color, I think you could get a good idea.  As a side note, a true rose/chocolate nose is paired with hazel eyes and brown paw pads.  They are born with a pink nose which turns into a true chocolate colored nose.  Many dogs noses are black but fade and look brown; they may look brown are not genetically brown.

Easy to see where the beautiful coat comes from - yes, black is dominant and the parti markings are apparent.  In genetics you can't get certain colors without others present, it's fascinating!   

Gorgeous pup~
