The 39 signature strains all cross with each other, every pair of them, with none left out. That is 741 crossings: 57 of them make another signature strain, and the other 684 are the register - crosses nobody wrote, that the game generates, and that the first player to breed one gets to name.
4 of 39 have been bred by somebody. A line is drawn, and a crossing marked, only where both ends have a name. So this starts as a silhouette and fills in as the world plays - which is the same thing the register does, seen all at once.

The signature strains
Six tiers, and a line from the parent a strain descends from. The other parent of each recipe is in the table below, where it can be read as words. The diagram and the table are each one size at every screen - on a narrow one, drag them sideways, or read the printed list instead.
Each strain against every strain before it, once - 741 cells, no diagonal, because a strain does not cross with itself. Pick a strain to light its row and its column.
Every crossing of two signature strains. Each row is one strain and each column is another; the cell where they meet is what they make. An empty cell means nothing about that crossing is public yet.
One of the 39. It came with the mod and already has a name, so there is none to claim.
Named
Somebody got there first and named it. That name is in everybody's game.
Bred, not named
On the register, with nobody's name on it yet.
Empty
Nothing about this crossing is public yet. It may be one of the 57 that makes a signature strain, or one of the 684 nobody has bred - the sheet does not say which, and finding out is the game.
