Aug 19, 2011 · In the PLOS Biology article, A Simple Genetic Architecture Underlies Morphological Variation in Dogs, scientists are examining what causes dogs to look the way they do.

Apr 25, 2020 · Our results identify variants of the strong impact associated with 16 phenotypes, including bodyweight variation which, when combined with existing data, explain greater than 90% of body size variation in dogs.

Explore the fascinating world of genetic variations in dogs. From breed diversity to health implications, delve into the complex DNA that shapes our canine companions.

Mar 5, 2008 · Dogs are highly unusual in their variation, from the Chihuahua to the Great Dane. (Recently, body size was found to be largely explained by differences in a single gene among dog...

May 1, 2023 · In a recent study, scientists compiled DNA sequences for more than 4,000 domesticated and wild dogs to uncover the genetic connections between them and found that they sometimes defy the...

Oct 2, 2019 · Genetic and phenotypic variation across dog breeds provides a unique opportunity for investigating questions about the evolution and biological basis of complex traits.

In a new study, researchers at the National Human Genome Research Institute (NHGRI) have generated the largest catalog of genetic variants associated with physical traits for …

DNA structural variation (SV) comprises a major portion of genetic diversity, but its biological impact is unclear. We propose that the genetic history and extraordinary phenotypic variation of dogs make them an ideal mammal in which to study the effects of SV on biology and disease.

Dec 8, 2022 · We identify ten major canine genetic lineages and their behavioral correlates and show that breed diversification is predominantly driven by non-coding regulatory variation.

Over the past three years, researchers have identified dozens of genetic variants that influence breed-defining traits, including those for skeletal size, coat color, leg length, hairlessness, wrinkled skin, hair length, curl and texture, and the presence of a dorsal fur ridge.
