how did i get killerbee.. is that super pastel x super spider??
how many %?

Killer bee is a combination of super pastel and spider. The usual way to get it is to cross a bumblebee with a pastel. Each of their eggs has a 1/8 chance of hatching out a killer bee. There are other matings with a higher probability of producing a killer bee, but the parents are harder to find and more expensive.

biggest thing to remember is the what makes the killer be is the super pastel spider genes. The only way you can get a super pastel gene is if both parents have the pastel gene. So a bumble bee x normal pastel, Bumble bee x super pastel, bumble bee x bumble bee, Kille bee x bumble bee, killer bee x pastel, and so on, There are many ways to get a killer bee and different odds for every pair. Just remember both parents need the pastel gene and at least on need the spider gene.

You Odds will differ with you different pairings. Do you know how to work a punent square to figure these out?

actually..no..i am new in breeding ball python..but i am planning to have a pair of spider and pastel...thank for your ans..

Take some time and look around online for how to make punett square. It can be cofussing in the beginning and that is why a lot of people just ask on KS so they don't have to learn but I would encurage you to take some time to start learning them and then use KS as a source to double check your anwsers. The nice thing about Punett squares is they seem confussing but once you figure them out they become a snap!!! and before long you can start planning out all to possiblities for your future projects!!! Also don't only figure out the odds of what you have in stock but what you want to make, then start looking ato possible routes to make it and see the different odds. You may find out that there are a few different routes and the way you thought would pay off the best may not. Trust me it is fun in the long run.

Just my two pennies,

ok..thank a lot..but..can you tell me where can i find the information and learn..sorry for i am so stupid as i am relly new in breeding ..

Running a google search for "ball python genetics" will give you a number of places to begin learning about the genetics. Two top links which look very accurate are:
http://www.newenglandreptile.com/genetics_simple_recessive.html
http://www.ballpython.ca/genetics.html

The first link shows the "Punnet square" method, and will get you started with simple genes then show more complicated ones. The combo you are looking for (killer bee) requires two independent genes, one of which is dominant and the other of which is the homogeneous form of a co-dominant gene. This means that you MUST have either a bumblebee or a killer bee to produce a killer bee, and you must cross it against a pastel, super pastel, bumblebee, or killer bee.

The least expensive way would be bumblebee to pastel, which gives a 1/8 possibility that each offspring will be a killer bee. A better way would be a bumblebee and a superpastel, which gives you a 1/4 KB offspring. Better yet would be a super pastel and a killer bee, which will produce 1/2 killer bees. Best is two killer bees, which gives you 3/4 offspring as killer bees.
