I feel like now that this thread has been started, it might be a good place to throw a thought I’ve wondered about for a long time–ever since I originally got typed and my result was something I didn’t expect, but with signal mixing with the type I did expect.
I’ve noticed that anecdotally, people often belong to the same quadra as a parent or parents. And it is of course still unknown what our genes might say about type. I wonder if it’s also possible to be primarily one quadra, but then either develop signal mixing as a result of copying a parent’s mannerisms, and/or a heredity effect such as incomplete dominance, or polygenic traits.
