Genetics: Difference between revisions

 

The game considers certain eye colors and hair colors as dominant and some as recessive.<ref>Hair that is in the "custom" bin, whether Maxis-made or [[custom content]], is treated differently. See the section on [[Genetics#Custom phenotypes|custom phenotypes]].</ref> If a baby gets a dominant and recessive gene for eye color or hair color, the dominant color will always be visible. However, if the baby gets two dominant (or recessive) genes for eye color or hair color, one will be randomly selected as "dominant". That color will be visible, and that gene will show as "dominant" in SimPE. The other will be carried as a recessive, and will be shown as such in SimPE. It should be noted that, while alien eyes are dominant, the alien eyes will look identical to brown ones, should the Sim not also express the alien skin tone.<ref>According to [http://www.moreawesomethanyou.com/smf/index.php?PHPSESSID=9c755f96123bff0fb549917b8bc5dc50&topic=13761.msg392568#msg392568 this post] by Pescado, the [http://www.moreawesomethanyou.com/smf/index.php/topic,1482.html creaturefixes] mod from [[More Awesome Than You]] will allow Sims without the alien skin tone to express alien eyes.</ref>

 

Skin tone is passed in the same way. However, if a Sim receives two genes for normal Maxis skin tones, those genes define the ends of a range in which 1 is light skin, 2 is tan, 3 is medium, and 4 is dark. Within that range, all skin tones are equally likely, and which one the baby has is determined at random. For example, a baby who gets a gene for tan skin and one for dark skin may have tan, medium, or dark skin. In SimPE, these genes will be shown as "SkintoneRange". While one will be shown as "dominant" and one as "recessive", the game itself does not treat any normal skin tone as dominant.
