I know it should be simple and I think I know how it works, but I just want to be sure. Lets say I have a bumblebee and breed it to a normal. Should I come out with 50% bees, 25% pastels and 25% spiders or 25% bees, spiders, pastels and normals? Once you get out of the realm of breeding a one morph codom to a one or two morph codom how do the statistics work then and when they hatch out how do you know which morph they are? Like if I had a spinner blast x dessert fire enchi. What would come out of that?

Give this a try:
Advanced Genetics Wizard

This will allow you to put in multiple traits for each parent and will generate the percentages you are looking for. You must know the traits that make up the morph you are interested in. For instance, Bumblebee is made up of Spider and Pastel, so 2 separate abnormal traits.

okay i think I know this one.. LOL
if you breed a bee to a normal you should get pastels, spiders and normals. And if you breed a bee to a pastel, i think that is how you get killer bees. Someone please correct me if I'm wrong. But i'm pretty sure you wont get bees from that pairing because a bee is a spider X pastel breeding.

you should have a 25% chance of getting a bee out of each egg.

A Bee IS a spider X pastel but it doesn't have to come from a spider to a pastel. In this case the male carries both spider and pastel traits so this pairing should produce 25% bees, 25% spider, 25% pastel and 25% normal...potentially.

i'm sorry i was wrong.. i knew that each parent had to carry a spider or a pastel gene, but I didnt think about one parent carrying both.. DUH.

Flip a coin twice for every egg you get..If you get heads twice it would be a bee.If you get tails twice then it would be a normal.If you get heads once and tails once then it would be either spider or pastel.

Or just read these pages by Markus Jayne..

The simplest way really is to draw it out instead of just throwing the numbers around.

To make it simple we'll use S for spider and P for pastel.

Let's say its your male that is a bee. That means he has SsPp. Each locus (spot for that gene) has two alleles. So he's got one Spider gene - S - and one normal - s - in that spot. He also has one pastel - P - gene and one normal - p - in that spot.

With the female being normal, she would have all of the normal genes - sspp

Then just draw a little chart with the combinations you can have. And remember, each parent will only give one of their two alleles. I'll put the male genes across the top and the female genes down the side.

SP | Sp | sP | sp
sp | SsPp|Sspp|ssPp|sspp

I only listed the female combination of sp once, since she is guaranteed to give those alleles since she is normal. But as you can see, there are 4 combinations from the male.

So from this you have:
1/4 or 25% bee - SsPp
1/4 or 25% spider - Sspp
1/4 or 25% pastel - ssPp
1/4 or 25% normal - sspp

Hope this helps a bit.

Sorry. That chart was bad. I did it in an image here to show it a bit better.
