It has become readily apparent that there is a slew of information (and misinformation) abounding in the TS3 Equine community at large about coat color and the genetics behind it.
The Hoffman online generator is commonly used to generate an example phenotype, or "look", but it needs to be used with the full understanding that it's genetic coding is incomplete and obsolete. For example, it gives the possible combination of To/To-Rn/Rn-W/n even though this is a real world genetic impossibility. Granted she has linked Cream and Pearl properly, but it took her many years to do so after the research on Pearl was made public.
There are many other such calculators available and most are not up to date as relates their coding to real world DNA research. When used in concert with an understanding of which genes can and can not safely co-exist then they are an invaluable tool. Used indiscriminately they can cause problems for anyone who purchases one of your horses.
Before anyone gets to thinking I have it in for Ms. Hoffman, wiki is also misleading in a number of areas. Generally speaking, Wiki (of which I am an editor) is grossly limited in exactly what they can include and when it may be included. Appaloosa Project limiting their early research and data to only paid subscribers, and other working-groups following suit, makes it difficult for such sites as wiki to be fully updated as there are no publicly available links for the editors to include on the wiki pages. The research data IS out there, if one chooses to hunt for it. It's just not always easily accessed and sites such as wiki demand such access before the data can be included.
The enclosed Genetics Guide is written to further the understanding of the players of The Sims 3: Pets in the breeding, raising, and playing of horses when it is desired to use real world genetics for the most realistic experience. It is recognized that not every player will decide to use real world DNA in regards to their pixilated ponies and should in no way be assumed that we advocate for any player to do thus; we only wish to help those players who strive for the utmost realism.
Please know that while all this seems really involved we will endeavor to keep this guide as simple and easy to understand as possible. Though it is sourced in real world Genetic Science, it is written in plain speak and with simplified notation (No Eat/ea-A+/a- here).
Many Thanks to "Pony S.", also known as Sunny Edelweiss on Equus-Sims forum, for making sure I stay up to date on the latest developments. Also to her network of Equine Color Gene research buffs who never hesitate to correct my mis-identifications or to point me in the direction of a newly published paper.
