No not completely but I know what that software is used for. A breeder had sent that my way a little while ago when her and I were discussing recessive genes, dilute genes, etc.
It's supposedly good for marking / tracking genes within a line and is good for computing results of line breeding, etc. Marks genes such as color, etc and supposedly is a good tool, but it's a little scientific. There's some other decent software on that site as well.
