I am starting to do a little research as to the passing on of genetic traits. I recently came into possession of a nice pair that have been together for about two years, one Black O. (male) and a normal O. with a bit more of a redish hue than is normally found. This got me thinking and I was wondering if there is a source that describes which traits may be dominant or recessive when it comes to stripes or color pattern? I am curious as to if these two guys would produce black, orange, or a mix of the two traits?
