Omg, it's been so long since my last post here

.
This explication is very simple!
Circle back and jungle are minor changes in the pattern of the spots. Lets say you are born with frickles on your nose but your parents dont have any... You aren't another race or morph... It's just a little modification on your chromosomes.
Leos are like humans, everyone is unique. not every person has the same traits. Leopard gecko females dont clone themselves so its only normal to have a difference with the parents.
I hope this helped

. If you have more questions about genetics you can send me a pm.
