1.0 2.0 .1 - What does it all mean?

Ok so pardon my ignorance but I'm new to BP keeping and am curious what these numbers mean when listed next to a morph.

1.0
.1
etc.


Thanks for any and all responses keeping me informed.

It's an indication of gender. :)
1.2.3 means 1 male, 2 females, 3 unsexed.
