Disclaimer: Before reading through this site, please note that I am not a geneticist or a professional scientist (please see the "About Me" pages). I am a layperson with an interest in genetics, and particularly in making colour genetics interesting and easy to understand for everyone. This site is intended as an introduction to colour genetics in dogs, and while I do my best to ensure its accuracy, please do make sure to do further, independent research if you want to find out more. All of the pages on this site provide links to sources that are a great place to start your research.
Please also note that I am not always able to keep fully up to date on new discoveries in dog genetics, so if you do spot anything that's out of date, please let me know. Make sure to include links to your sources (i.e. published scientific studies).
