After reading some of the previous post from several years ago up until recently, it's safe to say most of us on here live dogs and love to understand what makes them tick, genetics, health care and such.
With that rambling said figured some of you would enjoy this short genetics video, after watching it and applying that to dogs it's made the way I see things and breeding dogs from a different angle now.

Genetics video....
Re: Genetics video....
I agree in the importance of a healthy diet and the effect and importance of the environment, however there is no way such drastic changes in color and size could happen in a single generation of genetically identical mice. Notice she is only showing two mice, what happen to the rest of the litter and what was the color of their recent ancestors? The truth, there were some of each of the colors she shows, within the last 20 generations regardless of what they feed them and that is the main reason of the differences in color and size.
Re: Genetics video....
Honestly I'm opening my mouth prior to watching the video. That said I promise I will.
However genetics is not as simple as taught in most classes even college level. Each animal species follows some general rules but the oddities hidden in their DNA varies and the results of selective breeding can be surprising. The Russians devoted a lot of resources to this as did the Germans. The Russian information isn't as readily available to us English speakers. It doesn't have the creepy overtones of the German research and is extremely well documented and performed multiple times before accepted.
Its worth looking into if you have more then a passing interest in the vast array of phenotypes hidden in many species.
