I've been doing some research on the matrix bloods recently, and so far I am having a difficult time differentiating between some of the matrix's I've seen and just normal bloods. Some of them seem to have a much more busy pattern that is easy to tell apart, but many others that I have seen look like normals to me. So the question is, what are the specific visual traits that define a matrix?

The reason I ask is because I currently have a 2011 blood female that I purchased about a year ago. At the time they told me that the father was a matrix, the mother a normal, and that she was one of the normals in the clutch. I didn't think much of it at the time because I knew the matrix was a dominant trait. Recently I started doing some research on some of the blood morphs because I am looking at getting a male, and I noticed that many of the pictures that I saw of the matrix looked strikingly similar to my little female. So I started thinking that maybe there is a possibility that she is a matrix? Unless there is some important trait that I am missing.

Overall I'm just very confused about what the matrix is supposed to look like due to the very different patterns of them I have seen. If anyone could clarify it would be a great help.
