The genetic differentiation of dog breeds has led to alterations in metabolism

A recently published article shows that canine breeds can be distinguished by alterations in their lipidome. The study of Lloyd et al. (2017) examined lipidome differences in 100 dogs from 9 different breeds. The study showed distinct inter-breed differences in the breeds’ lipidomes. This study highlights that the genetic differentiation of dog breeds has resulted in alterations in metabolism.

Recessive Black (allele a) - Latest Addition to MyDogDNA Color Tests

The MyDogDNA test panel includes now a new genetic test for coat colors: The a allele in the color locus A. The result is available to all MyDogDNA 2015 tested dogs on the "Traits" tab.

The A-locus, also known as the ASIP gene, affects the production of the pigment molecule responsible for black color. Four different alleles are known at the A locus: ay, aw, at and a allele.
