Are twins ever identical?

<< < (3/5) > >>

J. M. Pescado:
Truly "identical" twins occur only by pure coincidence. There is no mechanism in the game that actually generates true "identical" twins, and twins are no more similar than any other two random siblings. In fact, you are more likely to get "twins" due to the firstborn effect than you are through actual twin births, which will always be seperate sequence values and therefore likely different in personality: The firstborn effect assures an identical personality, whereas getting the same personality by random sequence repeat is much less likely. Then, for twins to be identical, they have to inherit the same genetic parts from both parents. The probability of all that happening is rather low. There's maybe 10 or so sim facial features, like "brow", "eye", "jaw", cheek", etc., so figure you're looking at something on the order of 1/1024 chance of it happening, assuming no "dominant" features with elevated probability.

FourCats:
In my game, I have 2 families that have twins that I consider "identical".  They may not be exact copies, but look very much the same as it is easy to get them mixed up.  I think that's close enough to call them identical.

One of these days I'm going to use Sim Surgery to attempt to transplant one sim's face onto it's twin.
