https://en.wikipedia.org/wiki/Labrador_Retriever_coat_colour_genetics There have been studies with that show that the black allele masks the Agouti locus rather than expressing the locus.[9] There is a lot of information on studies to be looked into, there are a few spelling errors that can be fixed, looking into the other colors of labs and how those are created.

Suggestions should be specific (e.g., which other studies should be looked into?) and content based rather than grammatical (spelling errors) Larson.309 (talk) 17:39, 12 October 2014 (UTC)

Wolves going through bottleneck after domestication
Different tests have been done to show the connection between wolves and domestic dogs. In an article published in PLOS Genetics, scientists did a study that compared the boxer, Croatian wolf, Israeli wolf, golden jackal, Chinese wolf, basenji, and dingo. They first looked at individual genomic sequences and compared them to population sizes of the species finding that wolves went through a bottleneck when they were domesticated. When phylogenetic relationships were studied, the scientists created a tree of the subjects they were testing. They used seven genomes to create the phylogenetic tree. They found 32% of variant sites were shared with dogs and wolves, 47.3% of variant sites were for wolves only, 20.2% of variant sites were for dogs only and 0.5% was fixed between dogs and wolves. The tree created had a 100% bootstrap support with jackals as an out group and boxers and basenjis more closely related to the dingo rather than the wolves. The next examined trait was tracing the domestication of dogs from wolves. They created a generalized phylogenetic coalescent-based model comparing population divergence times, ancestral population sizes, and rates of post-divergence gene flow with the seven genomes examined earlier. The result from this research was a realization of an even greater bottleneck after domestication than found earlier. The results of all of the examinations was the conclusion that wolves went through a population bottleneck, the first around 20,000 years ago and the second around 15,000 years ago. They also concluded that dogs diverged from wolves around 15,000 years ago due to gene flow from domestication Anderson.2207 (talk) 02:10, 14 November 2014 (UTC) Anderson.2207
