Parthenogenesis?

From what I understand, it would be like breeding the female to herself in punnet squares.
So YB x YB =
25% Super YB
50% YB
25% Normal

I think that's the right way to look at it, & explains why the 3 rat snakes I hatched out from apparent parthenogenesis are all very different. The 'mom' is a c/b cross of Yellow & Gulf Hammock rat snakes, & likely something else (Everglades +++)- or what I call a Florida mix, having spoke to the source when I acquired the 4 "Florida" rat snakes as 1.5 year-olds. Thanks.

Incorrect.

If mom is a YB and goes partho then she will produce only normals and Ivories. You will not get YBs from a partho clutch

So it has something to do with the egg self-fertilizing from whatever genetic info got sent to that specific egg? So each egg can be different, but every single allele is homozygous?

The second polar body fuses back in with the egg

All of the hatchlings should be the same sex as well, females in BPs IIRC?

As far as additional info for NicoleG:
The downside being that if they're partho, the likelyhood of them thriving decreases over time. They may hatch and do well for a while, but a lot of partho babies can start failing around the age of maturity (typically 2 years in BPs). This is why you may see breeders listing that the baby was partho in their info as well.
