Perfect Pairs!

This morning I opened an advertisement in my email box from Lord and Taylor- they are having a super sandal sale- and what do I see? I pittie mix features with the shoe-model! I was so excited, I looked into it and found out that it is indeed part of a campaign called "Perfect Pairs". They've teamed up with Best Friends and local shelters to host an adoption event in conjunction with their Sandal Sale.
Each of the dogs in their ads is up for adoption with the local partners! I love it!

Coat Color Genetics Revisited: White Coats

Last year, I wrote about the genetics of Brindle Coats (read more here.)

Here's what we learned: Dog coat color, shape, and length genetics are based in 16 specific locations of the geneome. The basic color loci are: Agouti Locus (A), Brown locus (B), Dilute locus (D), Extention locus (E), Harlequin locus (H), dominant black locus (K), Merle locus (M), and Spotting locus (S).

Still, this doesn't help the non-scientist understand the amazing differences you see among litter mates... well I recently discovered a little more information about white coats that is very interesting.

Just take a look at the litter from Smilin' Pit Bull Rescue that sweet, adoptable Mama-pittie Onyx delivered:
(Warning, cuteness overload below...)

Onyx, a black short-haired pittie with white spots, had two all-white girls (1 short, 1 long haired), three all-black boys (2 short, 1 long haired), and 1 short-haired brown boy.

But how did a Black dog have pure white puppies? Well apparently the same genes that code for the extension of black and brown pigmentation over the body are present in white dogs, but white dogs are lacking the genes that turn ON the melanin production: ie, inject the hair with melanin from the hair folacle.
