My Biology teacher told us not all genetic traits are as cut and dry as dominant and recessive. I had asked her why my skin color was neither like my mom who is extremely light or my father who is very dark. Im in between. She said skin tone was a trait that is different from the rest is that is can take on a mixture of both traits. Im guessing the same is true for hair patterns which means a 1 and 4 could make a 2.
Yes, it's real. No, you can't touch it.
