Im planning to get a Female Spider Ball python and a Male Pastel Ball python, if I breed them will I get Bumblebee? And does it really matter what kind of pastel? Like I like lemon Pastel, will that work?

Thanks

It does not matter what type of pastel you get so go with the one you like, but with pastel X spider, statistically you should get a bee or two...will you? there is no certianty, people miss the mark all the time.

Ok, Thanks for all the help!

You actually have a 25% chance. Then another 25% with a spider, 25% pastel and 25% normal.......Keep faith

...that the quality of the pastel will trasfer to the quality of the bee produced. get a pastel with lots of yellow and as little orange as possible. lemons are an exellent choice.

This is very true! The pastel is very important if you want to create nice looking bumblebees. I have seen BBs that have been produced from pastels that brown out to the point that they look like a normal as an adult and I honestly think that a regular spider looks better then those bumblebees. I have on the otherhand seen BBs that were produced from Lemons and Blondes that still retain there yellow with very little to no browning out as an adult. I suggest if you really are conserned with what your Bees will look like into adulthood then you should ask the seller for pics of the adults that produced the pastel you are inquiring about. That will give you some insight as to how yellow your bees will look like one day. Now granted, pastels do very per clutch, but your blondes and lemons consistantly produce higher quality pastels...............BELIEVE IT!

Like any het X het breeding (spiders and pastels are both heterozygous for their respective mutations) there is a 25% combined chance of getting the mutant gene from both parents. With each egg having an independent 25% chance of being a bee getting at least one depends on how lucky you are and how many eggs you hatch.

With 6 eggs you would have a 82% chance of producing at least one.

Actually out of 6 eggs his odds for a bee is 17% give or take.....lol

Here is how I figured it, did I do it wrong?

Each egg has a 0.25 chance of being a bee so a 1 - 0.25 = 0.75 chance of not being a bee.

The combined chance of all 6 not being bees is 0.75^6

Since you either get no bees or some (i.e. chance of 1 combined) the chance of getting one or more bees is:

1 - 0.75^6 = 0.82 or 82%

Randy is right. He is finding the probability that he will get AT LEAST ONE bee. If you know anything about combinations and permutations you can calculate it a different way. There are 4096 different combinations of offspring for 6 eggs. 3367 of those contain at least one bee; ie 82% of the combinations. Some contain 1 or 2 bees and maybe you hit the jackpot with 6 bees(very unlikely; .02% probability). But your probability to get one of those random 3367 combinations is 82%. Doing it this way is more difficult. Randy does it the easy way lol. We still get the same number though.
