What does this mean?

I've noticed before some names of morphs there is a decimal number (1.0, 0.2, etc). I do have knowledge of basic genetics but haven't really noticed these numbers until recently. Can someone please explain?

example

Spider 1.1.4

first digit is how many males owned.. second is females and third is unknown... usually you dont see too many third digits.

Unknown as in not sexed yet.

Thanks for the info! Makes total sense now!
